nb/intel/sandybridge: Refactor IOSAV_SUBSEQUENCE again 

To replace the register writes with assignments to struct fields, we
would need to have the values as parameters of a single macro. So,
split the raw value of `IOSAV_n_SP_CMD_CTRL_ch` in two parts. Note that
the single command that sets bit 17 is likely wrong, but it will be
fixed after refactoring. For now, we'll treat it as part of `ranksel`.

Move the parameters of `ADDR_UPDATE` into the top-level IOSAV macro.
Hopefully, this will be enough to replace the underlying implementation.

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.
