omap_hsmmc: update struct hsmmc to accomodate base address from DT

Existing driver gets the actual omap hammc base address + 0x100
bytes as the first 0x100 bytes is not used by the driver. But
with DM conversion the base address from DT is different, to
accommodate the offset adding res0[0x100] to struct hsmmc.
