This attribute allows the EFI_MMC_HOST_PROTOCOL interface to manage
multiple instances in one driver.
EmbeddedPkg/MmcDxe: Add Revision attribute to the EFI_MMC_HOST_PROTOCOL
Note: The ARM PL180 and Omap35xx MMC host drivers has been updated.

The MMC driver defaults to assume a card is not present. It then starts a timer in MmcDxeInitialize to check for card presence every 200ms.
However it does not immediately check to see if a card is present so if the EFI driver connection process occurs less than 200ms after the driver load, the connection process for partition
or filesystem drivers will fail because MediaPresent still is FALSE. To resolve this race condition, we need to immediately perform the presence check in the Start routine.
EmbeddedPkg/MmcDxe: Media ID Handling
Initialize the MMC device on Start or when presence changes instead of doing it on the Block IO calls. This way the layered drivers can be stopped and rebuilt with new Media IDs instead of
experiencing errors on calls to Block IO.

Before the SetBlockLength command was called prior to a Read or Write command.

The indexes have been reversed compare to the specification which
created confusions in some MMC responses.

2 High Density cards

In the former version, we were checking the card was in the new state (Standby state).
But the transition to the nez state is only visible in the response of the next command.
This commit removes the check on the MMC state.

Ensure the passed parameters are correct.

In the former version, the check was done for every BlockIo operation.
By using a periodical function, we check less time in consequence performance
are better.

The MMC controller might be ready for data but not be in a 'ready' state
to send or receive commands.
This fix waits for the MMC controller to be in the correct state.
