[PATCH 1/4] mmc: core: some definitions and type modifications for SDUC

[Ricky Wu <ricky_wu@realtek.com>]

Modified some type from "unsigned int" to "unsigned long long"
because SDUC need more bits address
Add some definitions for support SDUC
Add pointer ae(Address extension) to know support SDUC or not
