We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

When no PHYs are declared in the dwc3 node, the phy init fails.
This patch checks if the "phys" property is presend and reports
the error returned by dev_count_phandle_with_args().
This patchs also fixes the styles issues added in last commit.
This patch should fix the DWC3 support on the UniPhier SoC family.

DWC3 Ips can have more than 1 PHY for USB2 and 1 PHY for USB3, add support
for a generic number of PHYs and adapt the code to handle a generic
number of PHYs.

DWC3 USB3 controllers will need USB3 PHY to be enabled, in addition to
USB2 PHY, to be functional. Therefore enable USB3 PHY when available.

Refractor PHY get/init/poweron and PHY poweroff/exit operations into
separate function so that its easy to support multiple PHYs.

It is wrong that expect .phy_init() to also power on the PHY. Therefore,
explicitly, call generic_phy_power_on() after generic_phy_power_init() in
order to power on PHY before using it.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

As per dwc3 databook, delay is required before taking the core out of reset.
This delay is required so that the PHY are stable, and then we can take core
out of reset.
