On SH, as of 37b7a97884ba64bf7d403351ac2a9476ab4f1bba we have to use the
endianess-agnostic I/O accessor functions.
In commit bf5f0019046d596d613caf74722ba4994e153899, Heiko fixed this for 32-bit
PowerPC; my patch now generalizes upon that.
The device is now recognized correctly for both litte-endian and big-endian
sh7785lcr, but I have not tested this any further, as the board is situated in
a remote data center.
