ARM: 7631/1: mmc: mmci: Add new VE MMCI variant
The Versatile Express IOFPGA as shipped on VECD 5.0 (bitfiles v108/208 and v116/216) contains a modified version of the PL180 MMCI, with PeriphID Configuration value changed to 0x2. This version adds an optional "hardware flow control" feature. When enabled MMC card clock will be automatically disabled when FIFO is about to over/underflow and re-enabled once the host retrieved some data. This makes the controller immune to over/underrun errors caused by big interrupt handling latencies. This patch adds relevant device variant in the driver.
