NO_RANKSEL was introduced because it appeared less often and it did not
cause any lines to become too long. To simplify macro transmutation, add
the RANKSEL opposite and keep NO_RANKSEL as a no-op to ease replacement.

complicates search and replace operations, and wil be taken care of in
subsequent commits.

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.

Lower 20bits of TOLUD register include 19 reserved bits and 1 lock
bit. If lock bit is set, then northbridge.asl was reporting the base
address of low MMIO incorrectly i.e. off by 1. This resulted in Linux
kernel complaining that the MMIO window allocated to the device at the
base of low MMIO is incorrect:
pci 0000:00:1c.0: can't claim BAR 8 [mem 0x7fc00000-0x7fcfffff]: no compatible brw
pci 0000:00:1c.0: [mem 0x7fc00000-0x7fcfffff] clipped to [mem 0x7fc00001-0x7fcfff]
pci 0000:00:1c.0: bridge window [mem 0x7fc00001-0x7fcfffff]
This change masks the lower 20 bits of TOLUD register when exposing it
in the ACPI tables to ensure that the base address of low MMIO region
is reported correctly.
TEST=Verified that kernel dmesg no longer complains about the BAR at

spd_cache. It's for reducing the SPD fetch time when device uses SODIMMs.
The MRC cache also includes SPD data, but there is no public header file
available to decode the struct of MRC. So SPD cache is another solution.

BRANCH=None
TEST=Build puff successfully and verified below two items.
one DIMM save the boot time : 158ms
two DIMM save the boot time : 265ms

This patch adds the get_spd_sn function. It's for reading SODIMM serial
number. In spd_cache implementation it can use to get serial number
before reading whole SPD by smbus.

BRANCH=None
TEST=Wrote sample code to get the serial number and ran on puff.
It can get the serial number correctly.
