clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks

Browse source 
commit e8b63288b37dbb8457b510c9d96f6006da4653f6 upstream.

hclk_cpubus needs to keep running because it is needed for devices like
the rom, i2s0 or spdif to be accessible via cpu. Without that all
accesses to devices (readl/writel) return wrong data. So add it
to the list of critical clocks.
