Revert "Byte swap to support BGRA in recovery mode"

This reverts commit e5879c3639789d61803605c12371a4f291e0b3cc.

The swap in page flip code is not needed any more.
New changes take care of ABGR and BGRA formats swapping bytes in
png and drawing routines

See commit fd778e3e406a7e83536ea66776996f032f24af64
