ARM: shmobile: r8a7778: cleanup registration of sdhi

sdhi driver which needs platform data at the time of
registration is used from BockW only.
Now, ARM/shmobile aims to support DT,
and the C code base board support will be removed
if DT support is completed.
Current driver registration method which needs platform data
and which is not shared complicates codes.
This means legacy C code cleanup after DT supporting
will be more complicated
This patch registers it on board code as cleanup C code
