mmc: sdhci-iproc: Apply caps from bcm2835-mmc driver

Since the mmc module on bcm2835 neither provide a capabilities register nor
free documentation we must rely on the downstream implementation [1].

So enable the following capabilities for bcm2835:

MMC_CAP_MMC_HIGHSPEED
MMC_CAP_SD_HIGHSPEED
MMC_CAP_DRIVER_TYPE_A
MMC_CAP_DRIVER_TYPE_C
