ARC: Fix ICCM & DCCM runtime size checks
[ Upstream commit 43900edf67d7ef3ac8909854d75b8a1fba2d570c ]
As of today the ICCM and DCCM size checks are incorrectly using
mismatched units (KiB checked against bytes). The CONFIG_ARC_DCCM_SZ
and CONFIG_ARC_ICCM_SZ are in KiB, but the size calculated in
runtime and stored in cpu->dccm.sz and cpu->iccm.sz is in bytes.
Fix that.
