The MIO clock is enabled by default, and the STDMAC clock is
enabled by the clk driver. The ad-hoc way to enable the clock
is no longer needed.

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.

Starting from PXs3, the bit fields of RSTCTRL, CLKCTRL registers
will change every SoC. There is no more point to define bitfields
in the common header file.

In order to be able to migrate the various SoC EHCI CONFIG options we
first need to finish the switch from CONFIG_USB_EHCI to
CONFIG_USB_EHCI_HCD.

Set the same PHY parameters as the Boot ROM uses.

For LD11 and LD20 SoCs, the RST_n pin is asserted by default. If
the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device
would stay in the reset state until its RST_n pin is deasserted by
software.
Currently, this is cared by an ad-hoc way because the eMMC hardware
reset provider is not supported in U-Boot for now. This code should
be re-written once the "mmc-pwrseq-emmc" binding is supported.

The current implementation has ugly switch statements here and there,
and duplicates similar code. Rework it using table lookups for SoC
data and reduce code duplication.

The USB boot without the stand-by MPU is available on ES3 or later
of LD11 SoC, but the code in this if-conditional block must not be
run when booting from USB. Check if the boot device is USB, and
skip the code in the case.

At the moment, the clk driver is not clever enough to automatically
enable parent clocks like Linux. Enable the STDMAC clock explicitly
if USB is enabled.
