mmc: extend mmcinfo output to show partition write reliability settings
This extends the mmcinfo hardware partition info output to show
partitions with write reliability enabled with the "WRREL" string.
If the partition does not have write reliability enabled the "WRREL"
string is omitted; this is analogous to the ehhanced attribute.
Example output:
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
Erase Group Size: 8 MiB
HC WP Group Size: 16 MiB
User Capacity: 13.8 GiB ENH WRREL
User Enhanced Start: 0 Bytes
User Enhanced Size: 512 MiB
Boot Capacity: 16 MiB ENH
RPMB Capacity: 128 KiB ENH
GP1 Capacity: 64 MiB ENH WRREL
GP2 Capacity: 64 MiB ENH WRREL
