If anyone has any objections, please let me know. ------------------ From: Alexander Kochetkov 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.
