[PATCH v2 1/3] drivers/block/xsysace - replace in(out)_8/in(out)_be16/in(out)_le16 with generic iowrite(read)8/16(be)

[Alexey Brodkin <Alexey.Brodkin@synopsys.com>]

in(out)_8/in(out)_be16/in(out)_le16 are very powerpc/microblaze
specific. To enable use of Xilinx System ACE driver build for other
architectures (for example it's possible to use it on Xilinx ml-509
board with ARC700 CPU in FPGA) we need to use generic implementation of
accessors.
