This function was copy-pasted, comments included, from Sandy Bridge.
However, it is only called with 0x0044 as the northbridge's PCI ID.
Therefore, `bridge_silicon_revision() & BASE_REV_MASK` will always
evaluate to 0x40, which never equals `BASE_REV_SNB`, that is, 0x00.
As the condition is always false, treat this code as dead and drop it.
Following a similar reasoning, all direct comparisons against SNB
steppings will always be true, because `bridge_silicon_revision()`
returns at least 0x40 which is always larger than either `SNB_STEP_D0`
or `SNB_STEP_D1`. So, drop all but the code path that is actually used.

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.
