In EDK2, identifiers carrying the EFI prefix are reserved for ones
that are defined in the UEFI or PI specifications.
Since the MMC host protocol defined in EmbeddedPkg is not the one that
the UEFI spec defines, and given the confusion around this, let's rename
it to from gEfiMmcHostProtocolGuid to gEmbeddedMmcHostProtocolGuid.

The 3rd and 4th parameters of the CloseProtocol() call are wrong.
Given that we're not dissociating a child controller from a parent
controller (= closing a BY_CHILD_CONTROLLER open), but closing a BY_DRIVER
open, the 4th parameter (ControllerHandle) should equal the 1st parameter
(Handle).
It's unclear why this code hasn't crashed before.
Note that the patch doesn't fix the underlying driver model bug. I don't
understand what the loop in MmcDriverBindingStop() attempts to do. Is this
driver supposed to be a bus driver? It seems to create new handles, and to
append device path nodes. But it doesn't set up proper parent/child
protocol opens, and it doesn't close them.

ExtCSD structure may be read via DMA. So align it to

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.

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.
