[[PATCH v2] 2/7] EmbeddedPkg: Fix DwEmmc driver bugs

["Loh, Tien Hock" <tien.hock.loh@intel.com>]

From: "Tien Hock, Loh" <tien.hock.loh@intel.com>

Clear CTYPE on initialization. This is important if previous bootloader
changes the CTYPE can cause the controller to not initialize correctly
if CTYPE is not reset to 0
