ARC: Invalidate instruction and data caches early on boot

This is useful to make sure no stale data exists in caches after bootloaders.

The worst thing could be some lines of cache were locked in a bootloader
for example during DDR recalibration and never unlocked. This may lead
to really unpredictable issues later down the line.
