Add the necessary clock parts for:
- VDEC_1: used to feed VDEC_1
- VDEC_HEVC: the "back" part of the VDEC_HEVC block
- VDEC_HEVCF: the "front" part of the VDEC_HEVC block
In previous SoC generations (GXL, GXBB), there was only one VDEC_HEVC
clock, which got split in two parts for G12A.

Add the PCIe reference clock feeding the USB3 + PCIE combo PHY.
This PLL needs a very precise register sequence to permit to be locked,
thus using the specific clk-pll pcie ops.
The PLL is then followed by :
- a fixed /2 divider
- a 5-bit 1-based divider
- a final /2 divider
This reference clock is fixed to 100MHz, thus only a single PLL setup
is added.

Add the Amlogic G12A Family CPU Clock tree in read/only for now.
The CPU clock can either use the SYS_PLL for > 1GHz frequencies or
use a couple of div+mux from 1GHz/667MHz/24MHz source with 2 non-glitch
muxes.
Proper DVFS support will come in a second time.
