[ 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()
