Reading the SPD using the SMBUS routines takes a long time because each
byte or word is access seperately.
Allow using the i2c read eeprom routines to read the SPD. By doing this
the start address is only sent once per page.
The time required to read a DDR4 SPD is reduced from 200 msec to 50
msec.

If panel has too small hfp or hbp, hfp_byte or hbp_byte may become
very small value or negative value. When very small value or
negative value is used, the panel will be scrolling or distorted.
This patch adjusts their values so that they are greater than
the minimum value and keep total of them unchanged.
DSI transfer HBP or HFP, There are some extra packet. ex. packet
header(4byte) and eof(2byte) and (next)hs packet header(4 byte).
the hfp_byte = HFP * BPP - packet header(4byte) and eof(2byte)
and (next)hs packet header(4 byte). So the min hfp_byte is 2 when
HFP = 4.
This is equivalent to the Linux kernel DSI change in:

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
base of low MMIO.
