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.
