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.

The new SoC PXs3 changed the address of PLL, but still uses the
same PLL name. We can not define SC_*PLLCTRL in the common header.
Move them to per-SoC .c file. Also, fix some PLL comments.

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.

- Initialize PLLs (SPL initializes only DPLL to save the precious
SPL memory footprint)
- Adjust CPLL/MPLL to the final tape-out frequency
- Set the Cortex-A53 clock to the maximum frequency since it is
running at 500MHz (SPLL/4) on startup

Initialize the DPLL (PLL for DRAM) in SPL, and others in U-Boot
proper. Split the common code into pll-base-ld20.c for easier
re-use.

The System Control block moved to a completely different register
map for ARMv8 SoCs, so it cannot be shared with the ARM 32-bit ones.
Define register macros in a new header file.
