4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Kochetkov <al.kochet@gmail.com>
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.
