Move these states from the DSDT to the SSDT. Override the default
configuration if the host has the following qemu commit:
commit 459ae5ea5ad682c2b3220beb244d4102c1a4e332
Author: Gleb Natapov <gleb@redhat.com>

Add PIIX4 properties to control PM system states.
This patch adds two things. First it allows QEMU to distinguish
between regular powerdown and S4 powerdown. Later separate QMP
notification will be added for S4 powerdown. Second it allows
S3/S4 states to be disabled from QEMU command line. Some guests
known to be broken with regards to power management, but allow to
use it anyway. Using new properties management will be able to
disable S3/S4 for such guests.
Supported system state are passed to a firmware using new fw_cfg
file. The file contains 6 byte array. Each byte represents one
system state. If byte at offset X has its MSB set it means that
system state X is supported and to enter it guest should use the
value from lowest 3 bits.

The ACPI 5.0 specification says:
7.3.4.4 System \_S3 State
[...]
* Dynamic RAM context is maintained.
[...]
This corresponds to the following in the PIIX4 spec:
PMCNTRL -- POWER MANAGEMENT CONTROL REGISTER (IO)
[...]
Bits[12:10] Suspend Type
[...]
001 STR (Suspend To RAM)
Also, this (ie. decimal 1) is the suspend type value that qemu recognizes
as an S3 (suspend to ram) request.
Only the value for PM1a_CNT.SLP_TYP is set (PM1b_CNT.SLP_TYP is left at
zero), since in OVMF we don't report the optional PM1b_EVT_BLK register
block to OSPM. (PM1b_EVT_BLK is defined as 0 in "Platform.h"; see "4.8.1.1
PM1 Event Registers" in the ACPI 5.0 specification.)

Adds a subset of the terminal I/O capabilities described in the Single Unix Specification, V4.
Supports:
Erase previous character. Default is Backspace or ^H
Erase line. Default is ^U
TAB characters are supported and, by default, are rendered as 8 spaces. They will still be read as a single TAB character.
Both Canonical and Non-Canonical modes are supported.
If a terminal device is opened with O_TTY_INIT in the mode, the device will be initialized to "sane" values for interactive use. It will be in Canonical mode, Enter will be translated to NewLine and on output, a NewLine is translated to CRLF. Echoing will be on, control characters are output as ^X, and TABs are expanded.
See the new <sys/termios.h> file for more information.

2. To be consistent, update PciCfgRead to support full S3BootScriptWidth(Uint8, FifoUint8 and FullUint8) like PciCfgWrite.
3. Use BuildLoopData() to get the addressStride and BufferStride to do PCI CFG operations.
4. Correct, refine and enhance some comments and debug messages.
