===============
[ Upstream commit 15b8d2c41fe5839582029f65c5f7004db451cc2b ]
In big endian mode regmap_bulk_read gives incorrect data
for byte reads.
This is because memcpy of a single byte from an address
after full word read gives different results when
endianness differs. ie. we get little-end in LE and big-end in BE.
