EmbeddedPkg/MmcDxe: invoke SetIos() protocol method to set speed and width
Add the interface to change the bus width and speed.
By default, MMC is initialized with 1-bit mode and less than 400KHz bus
clock. It causes MMC working inefficiently.
Set I/O bus width on both MMC controller and EXTCSD. Otherwise, it may
cause unmatched failure case. And support more timing mode, high speed,
HS200 & HS400 mode.
