There's only one clock controller on-board and it's custom for HiP04?

Since all those PLL settings are configured in bootloader, kernel
don't need to configure it again.

By the way, I don't have the manual to configure those PLLs. All the clocks
are defined as fixed in kernel side.

If all the clocks are fixed-rate, you don't actually need a driver
for them, just use the regular fixed-rate clock and define one
node per clock.
