This driver is able to reconfigure OTG controller into HOST mode.
Board can add board-specific initialization as board_prepare_usb().
It requires USB_ULPI_VIEWPORT enabled in board configuration.

Most of ehci-fsl header describe USB controller
designed by Chipidea and used by various SoC vendors.
This patch renames it to a generic header: ehci-ci.h
Contents of file are not changed (so it contains several
references to freescale SoCs).

Some host controllers need addidional initialization after ehci_reset()
In non-dm implementation it is possible to use CONFIG_EHCI_HCD_INIT_AFTER_RESET.
This patch adds similar option to ehci drivers using dm.

The 2nd usb controller on sun4i/sun7i has its base address 0x8000
bytes from the 1st one, rather then 0x1000. Also the ahb clk gates
are interleaved with the ohci clk-gates introducing a hole between

When 'usb start' is used, block devices are created for any USB flash sticks
and disks, etc. When 'usb stop' is used, these block devices are currently
not removed.
We don't want old block devices hanging around since they can still be
visible to U-Boot. Therefore, when USB is shut down, remove and unbind all
the block devices created by the USB subsystem.
Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.

For the case where an external VBUS is used, we should enable the external
VBUS comparator in the driver. This would prevent an unnecessary overcurrent
error which would then disable the host port.
The overcurrent condition was happening on the SoCFPGA Cyclone5 devkit, thus
USB was not working on the devkit. This patch fixes that problem.

USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec,
8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT,
so these two should be kept separate. As EPs are either BULK or INTERRUPT
(or ISO), it is fine to have one array per direction for all transfer
types (also see e236519b7365ef75c5da6a5623f0b03d9c00cfae).
USB device address is 7 bits, so a bus may have more than 16 devices.
Check the device number, as the DWC2 driver only supports BULK/ISO for
the first 16 devices.

CSPLITs for INTERRUPT transactions have to be scheduled in each microframe
following the SSPLIT. INTERRUPT transfers are executed in the next even/
odd microframe depending on the HCCHAR_ODDFRM flag.
As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have
failed (transport error) without the error being detected by the host
driver. If the last CSPLIT is not received within 4 microframes after the
SSPLIT there was a transaction error and the complete transaction has
to be restarted.

A transfer is completed if the XFERCOMP flag is set, irrespective of the
ACK flag. BULK OUT transfers to some HS devices complete without having
the ACK flag set, which signal the devices has responded with an NYET
to the transfer (PING protocol).
The new behaviour matches the Linux kernel minus any PING protocol.

Fix two errors in transfer len calculation, move loop invariant code out
of loop.
If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly
smaller), the xfer_len will be to large, e.g.:
xfer_len = MAX_TRANSFER_SIZE = 65535
max packet size = 512
=> num_packets = 128
=> IN xfer_len = 65536
For OUT transactions larger than (65536 - mps) bytes, the xfer_len
determination is quite awkward, it is only correct due to:
- max_packet_size for control/bulk/interrupt is required to be
power-of-two.
- (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero
for all allowed (2^3 ... 2^9) packet sizes
As the max xfer len is loop invariant, it can be moved out of the loop.

With the old order of initialization the hcor pointer has been setup to
the same address as Exynos EHCI base address (0x12110000 instead of
0x12110010).
Such behaviour was caused by reading value of 0 instead of 0x10 from EHCI
HCCPBASE register without doing proper clock initialization before.
To fix this problem hcor initialization has been moved after USB PHY setup.
Now ehci_readl(&ctx->hcd->cr_capbase) returns correct value.
