nvmem: cleanup dead code in Kconfig

There is already an 'if NVMEM' condition wrapping NVMEM_RCAR_EFUSE,
making the 'depends on' statement a duplicate dependency (dead code).

I propose leaving the outer 'if NVMEM...endif' and removing the
individual 'depends on' statement.

This dead code was found by kconfirm, a static analysis tool for Kconfig.
