This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit e8b63288b37dbb8457b510c9d96f6006da4653f6 ]
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.
