char/nvram: Allow the set_checksum and initialize ioctls to be omitted The drivers/char/nvram.c module has previously supported only RTC "CMOS" NVRAM, for which it provides appropriate checksum ioctls. Make these ioctls optional so the module can be re-used with other kinds of NVRAM. The ops struct methods that implement the ioctls now return error codes so that a multi-platform kernel binary can do the right thing when running on hardware without a suitable NVRAM.
