Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

asm-generic/io.h: add big endian versions of io{read,write}{16,32} 

The asm-generic/iomap.h provides these functions already, but the
non-generic fallback defines do not.
