[ Upstream commit 7727ec1523d7973defa1dff8f9c0aad288d04008 ]

Add missing post-increment operators for byte pointers in the
loop that copies remaining bytes in xemaclite_aligned_read().
Without the increment, the same byte was written repeatedly
to the destination.
This update aligns with xemaclite_aligned_write()
