Currently on image entry, the data cache in the RW address range is
invalidated before MMU is enabled to safeguard against potential
stale data from previous firmware stage. If PIE is enabled however,
RO sections including the GOT may be also modified during pie fixup.
Therefore, to be on the safe side, invalidate the entire image
region if PIE is enabled.
