mmc: core: Add members to mmc_request and mmc_data for CQE's

Browse source 
Most of the information needed to issue requests to a CQE is already in
struct mmc_request and struct mmc_data. Add data block address, some flags,
and the task id (tag), and allow for cmd being NULL which it is for CQE
tasks.
