Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.
Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.

This is a convenient way for a driver to get the hardware address of a
device, when regmap or syscon are not being used. Change existing callers
to use it as an example to others.

This patch enables the USB EHCI support for the Marvell Armada XP (AXP)
SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure
the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done
this already in the bin_hdr (SPL U-Boot). Without this, accessing the
controller registers in U-Boot or Linux will hang the CPU.
Additionally, the AXP uses a different USB EHCI base address. This
patch also takes care of this by runtime SoC detection in the Marvell
EHCI driver.

USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.
Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.
This patch removes the powering off calls, fixing the undesirable power
bouncing.
Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

Added 38.4MHz/48MHz entries to pll_x_table for CPU PLL. Needs
to be measured - should be close to 700MHz (1.4G/2).
Note that some freqs aren't in the PLLU table in T210 TRM
(13, 26MHz), so I used the 12MHz table entry for them. They
shouldn't be selected since they're not viable T210 OSC freqs.
Since there are now 2 new OSC defines, all tables (pll_x_table,
PLLU) had to increase by two entries, but since 38.4/48MHz are
not viable osc freqs on T20/30/114, etc, they're just set to 0.

On some single port (otg) controllers there is no emulated root hub, so
the first child (if any) may be one of: UCLASS_MASS_STORAGE,
UCLASS_USB_DEV_GENERIC or UCLASS_USB_HUB.
All three of these (and in the future others) are suitable for our
purposes, remove the check for the device being a hub, and add a check to
deal with the fact that there may be no child-dev.

Now that we unbind usb devices from usb_stop() usb_find_child() is
only necessary to deal with emulated usb devices.
Rename it to make this clear and add a #ifdef to make it a nop in
other cases.
Note the #ifdef turns usb_find_emul_child() into a nop, rather then not
building it and adding another #ifdef to the caller, this is done this way
because adding a #ifdef to the caller is somewhat hairy.

On an usb stop instead of leaving orphan usb devices behind simply remove
them.
The result of this commit is best seen in the output of "dm tree" after
plugging out an usb hub with 2 devices plugges in and plugging in a keyb.
instead, before this commit the output would be:
usb [ + ] `-- sunxi-musb
usb_hub [ ] |-- usb_hub
usb_mass_st [ ] | |-- usb_mass_storage
usb_dev_gen [ ] | `-- generic_bus_0_dev_3
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
Notice the non active usb_hub child and its 2 non active children. The
first child being non-active as in this example also causes usb_get_dev_index
to return NULL when probing the first child, which results in the usb kbd
code not binding to the keyboard.
With this commit in place the output after swapping and "usb reset" is:
usb [ + ] `-- sunxi-musb
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
As expected, and usb_get_dev_index works properly and the keyboard works.

The device-model usb_legacy_port_reset function calls the device-model
usb_port_reset function which is a 1 on 1 copy of the non dm
usb_legacy_port_reset and this is the only use of usb_port_reset in all
of u-boot.
Drop both, and alway use the usb_legacy_port_reset() version in
common/usb.c .
Also while at it make it static as it is only used in common/usb.c .

Without this we loose every other interrupt packet. We never noticed this
because with keyboards the packets which we were loosing would normally
be key release packets.
But now that we do keyrepeat in software instead of relying on the hid
idle functionality, missing a release will result in key repeat triggering.
This commit fixes this.
