The same workaround as ff999b8a0983ee15668394ed49e38d3568fc6859
"ARM: OMAP4460: Workaround for ROM bug because of CA9 r2pX GIC control register change."
need to be applied not only when system is booting, but when
MPU hits OSWR state through CPUIdle too.

Now the same issue is reproduced on boards PandaES and Tablet/Blaze with
SOM OMAP4460 ES1.0 when CONFIG_CPU_IDLE is enabled.
- GIC distributor is disabled
- scheduling is not performed any more
