Extend generic_setup_phy() parameter list with PHY mode and submode and
call generic_phy_set_mode() in generic_setup_phy(), so the generic PHY
setup function can configure the PHY into correct mode before powering
the PHY up.
Update all call sites of generic_setup_phy() as well, all of which are
USB host related, except for DM test which now behaves as a USB host
test.
Note that if the PHY driver does not implement the .set_mode callback,
generic_phy_set_mode() call returns 0 and does not error out, so this
should not break any existing systems.

Add two new callbacks matching the Linux ones. The .set_mode is used to set
PHY mode and submode, where mode is either USB, Ethernet, and so on, while
submode is e.g. for Ethernet case RGMII, RMII, and so on. The .set_speed is
used to configure link speed into the PHY. Unlike the existing configure
callback, which is used to pass arbitrary custom information to the PHY,
these two callbacks are used to pass standardized set of information to
the PHY.

Insert missing space in front of asterisk to avoid checkpatch warning.
Replace 'beeing' with 'being' as well, to fix another checkpatch warning.

In case PHY is not enabled, the generic_phy_configure() implementation is
missing. Add an empty one so that the list of empty functions is complete.

In drivers usb/host/{ehci,ohci}-generic.c, {ehci,ohci}_setup_phy() and
{ehci,ohci}_shutdown_phy() shares 95% of common code.
Factorize this code in new generic_{setup,shudown}_phy() functions.

Allow to disable PHY driver in SPL because it checks the CONFIG_SPL_PHY
variable for SPL builds.
The same change was done for usb by commit fd09c205fc57 ("usb:
s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/").

Add the PHY configure op callback to the generic PHY uclass to permit
configuring the PHY.
It's useful for MIPI DSI PHYs to setup the link timings.

Clients that are requesting some of uclass API's
without a device (with ofnode) usually have _nodev
naming convention.
- clk_get_by_index_nodev
- clk_get_by_name_nodev
- reset_get_by_index_nodev
- gpio_request_by_name_nodev
So, update the same naming convention PHY framework.
This doesn't change the existing functionality.

node is most of device related API's are termed as device
node and without device related API's are termed as ofnode.
generic_phy_get_by_node API is without device API, so fixed

This patch adds a "bulk" API to the phy API in order to
get/init/exit/power on/off a group of phys associated
with a device.
The bulk API will avoid adding a copy of the same code to
manage a group of phys in drivers.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The PHY framework provides a set of APIs to control a PHY. This API is
derived from the linux version of the generic PHY framework.
Currently the API supports init(), deinit(), power_on, power_off() and
reset(). The framework provides a way to get a reference to a phy from the
device-tree.
