nvmem: rmem: select CONFIG_CRC32

The newly added crc checking leads to a link failure if CRC32
itself is disabled:

x86_64-linux-ld: vmlinux.o: in function `rmem_eyeq5_checksum':
rmem.c:(.text+0x52341b): undefined reference to `crc32_le_arch'

          This driver maps reserved memory into an nvmem device. It might be
          useful to expose information left by firmware in memory.
