optee: add RPMB dependency

Browse Source 
Prevent build error when CONFIG_RPMB=m and CONFIG_OPTEE=y by adding a
dependency to CONFIG_RPMB for CONFIG_OPTEE so the RPMB subsystem always
is reachable if configured. This means that CONFIG_OPTEE 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_OPTEE
will remain unchanged.
