mmc: core: expose info about enhanced rpmb support
Following eMMC JEDEC JESD84-B51 standard, an ehannced form of
rpmb is supported. What this enhanced mode supports is in
addition to be able to write one rpmb or two rpmb frames at a
time, 32 frames can be written at a time.
Expose this information present in ext csd field so that the
user space application that wants to make use of this can do
so.
