[PATCH 04/10] clk: rockchip: rk3568: Use fixed PMU CRU base address for PLL access

[Jonas Karlman]

The RK3568 PMU PLL helpers lookup the PMU CRU udevice before accessing
PMU PLL regs. This may trigger a full PMU clock driver probe to get the
PMU CRU base address from the clock driver private data, something that
can take several ms.

Change to use the RK3568 specific PMU CRU base address consant directly
to simplify and remove the unneeded complexity of using runtime lookup
in SoC specific code.
