Joy Chakraborty 1c184baccf rtc: cmos: Fix return value of nvmem callbacks
Read/write callbacks registered with nvmem core expect 0 to be returned
on success and a negative value to be returned on failure.

cmos_nvram_read()/cmos_nvram_write() currently return the number of
bytes read or written, fix to return 0 on success and -EIO incase number
of bytes requested was not read or written.

Fixes: 8b5b7958fd ("rtc: cmos: use generic nvmem")
