clk: meson-g12a: add PCIE PLL clocks
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.
