[ARM] OMAP2/3 clock: don't tinker with hardirqs when they are supposed to be disabled
Clock rate change code executes inside a spinlock with hardirqs
disabled. The only code that should be messing around with the
hardirq state should be the plat-omap/clock.c code. In the
omap2_reprogram_dpllcore() case, this probably just wastes cycles, but
in the omap3_core_dpll_m2_set_rate() case, this is a nasty bug.
linux-omap source commit is b9b6208dadb5e0d8b290900a3ffa911673ca97ed.
