Routine Description:
Reads the next keystroke from the input device. The WaitForKey Event can
be used to test for existance of a keystroke via WaitForEvent () call.
Arguments:
This - Protocol instance pointer.
KeyData - A pointer to a buffer that is filled in with the keystroke
state data for the key that was pressed.
Returns:
EFI_SUCCESS - The keystroke information was returned.
EFI_NOT_READY - There was no keystroke data availiable.
EFI_DEVICE_ERROR - The keystroke information was not returned due to
hardware errors.
EFI_INVALID_PARAMETER - KeyData is NULL.
