nb/intel/sandybridge: Program IOSAV with macros
This is a temporary solution to simplify refactoring verification.
Programming a subsequence involves writing a group of four registers.
Abstract this into a "program subsequence" operation. This eliminates
register write noise, which should improve the readability of the code.
To replace the register writes with assignments to struct fields, we
would need to have the values as parameters of a single macro. So,
unroll SUBSEQ_CTRL and SP_CMD_ADDR into parameters of IOSAV_SUBSEQUENCE.
Line length limits are not for review. Breaking the lines unnecessarily
complicates search and replace operations, and wil be taken care of in
subsequent commits.
Tested with BUILD_TIMELESS=1, ASUS P8Z77-V LX2 remains unchanged.
