Subject: [PATCH net] net: emaclite: Fix missing pointer increment in aligned_read()

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()

Fixes: bb81b2ddfa19 ("net: add Xilinx emac lite device driver")
