mmc: extend mmcinfo to show enhanced partition attribute
This extends the mmcinfo command's output to show which eMMC partitions have the enhanced attribute set. Note that the eMMC spec says that if the enhanced attribute is supported then the boot and RPMB partitions are of the enhanced type. The output of mmcinfo becomes: Device: OMAP SD/MMC Manufacturer ID: fe OEM: 14e Name: MMC16 Tran Speed: 52000000 Rd Block Len: 512 MMC version 4.41 High Capacity: Yes Capacity: 13.8 GiB Bus Width: 4-bit User Capacity: 13.8 GiB ENH Boot Capacity: 16 MiB ENH RPMB Capacity: 128 KiB ENH GP1 Capacity: 64 MiB ENH GP2 Capacity: 64 MiB ENH Signed-off-by: Diego Santa Cruz <Diego.SantaCruz@spinetix.com>
