nb/intel/sandybridge: Use macros for JEDEC commands
Some commands, like ZQCS and ZQCL, use the same macro. This is because
they differ in things outside of the IOSAV_SP_CMD_CTRL registers. Also,
correct a comment that does not concur with the actual command in use.
With BUILD_TIMELESS=1, the binary of ASUS P8Z77-V LX2 remains identical.
