[PATCH 1/2] mmc: block: add RPMB dependency

[Jens Wiklander]

Prevent build error when CONFIG_RPMB=m and CONFIG_MMC_BLOCK=y by adding
a dependency to CONFIG_RPMB for CONFIG_MMC_BLOCK block so the RPMB
subsystem always is reachable if configured. This means that
CONFIG_MMC_BLOCK automatically becomes compiled as a module if
CONFIG_RPMB is compiled as a module. If CONFIG_RPMB isn't configured or
is configured as built-in, CONFIG_MMC_BLOCK will remain unchanged.
