mmci: Add support for ST Micro derivate
This patch adds support for the ST Microelectronics version of the PL180 PrimeCell. They use designer ID 0x80 and have a few alterations/bugfixes related to open drain and HW flow control. They also add some SDIO registers, I am unsure if these are in ST HW only or if this is things also added in later ARM revisions, but they are included in the mmci.h file for completeness.
