Add node "wp_grp_size", corresponding to WP_GRP_SIZE
(write protect group size) of eMMC's CSD register.

The eMMC card can be set into write-protected mode to
prevent data from being accidentally modified or deleted.
Wp_grp_size (Write Protect Group Size) refers to an
attribute of the eMMC card, used to manage write protection,
and is the CSD register  [36:32] of the eMMC device.
Wp_grp_size (Write Protect Group Size) indicates how many
eMMC blocks are contained in each write protection group on the eMMC card.
