Pierre Gondois 9006967c8d DynamicTablesPkg: Handle 16550_WITH_GAS id
Handle the EFI_ACPI_DBG2_PORT_SUBTYPE_SERIAL_16550_WITH_GAS
id when generating an AML description of a serial port. The same
_HID/_CID as the EFI_ACPI_DBG2_PORT_SUBTYPE_SERIAL_FULL_16550
are generated.

Pierre Gondois 691c5f7762 DynamicTablesPkg: Deprecate Crs specific methods in AmlLib
Some functions in the AmlLib have 'Crs' in their name and can only
be applied to '_CRS' AML objects. To re-use them on AML objects that
have different names:
 - Rename them and remove the '_CRS' name check.
 - Create aliases having of the 'Crs' function prototypes. These
   aliases are available when DISABLE_NEW_DEPRECATED_INTERFACES
   is not defined. They will be deprecated in a near future.

The deprecated functions are:
- AmlNameOpCrsGetFirstRdNode()
- AmlNameOpCrsGetNextRdNode()
- AmlCodeGenCrsAddRdInterrupt()

Pierre Gondois 0875443f7e DynamicTablesPkg: Extract AcpiHelperLib from TableHelperLib
The TableHelperLib contains helper functions. Some rely on
DynamicTablesPkg definitions (they use Configuration Manager objects).
Some others are more generic.

To allow using these generic functions without including
DynamicTablesPkg definitions, move them to a new AcpiHelperLib
library.

Joey Gouly 16136f218d DynamicTablesPkg: add validation for PcdNonBsaCompliant16550SerialHid
According to ACPI 6.4, 6.1.5 _HID states:

  - A valid PNP ID must be of the form "AAA####" where A is an uppercase
    letter and # is a hex digit.
  - A valid ACPI ID must be of the form "NNNN####" where N is an uppercase
    letter or a digit ('0'-'9') and # is a hex digit.

Joey Gouly 42c0019f27 DynamicTablesPkg: Add an override for 16550 HID in SSDT
Some platforms advertise support for a 16550 UART, but are not
compatible with the PNP0500 HID. Allow them to override the HID by
setting PcdNonBsaCompliant16550SerialHid.

Pierre Gondois bade7f423b DynamicTablesPkg: SSDT Serial Port Fixup library
According to Arm Server Base Boot Requirements,
Platform Design Document version 1.2 revision D,
September 2, 2019, section '4.2.1.8 SPCR'; The
SPCR console device must be included in the DSDT.

Additionally, it is often desirable to describe the
serial ports available on a platform so that they
are available for use by a rich OS.

To facilitate the description of serial ports on a
platform a common SSDT Serial Port Fixup library is
introduced. It provides interfaces to build a SSDT
serial port definition block table based on the
serial port information.

The SSDT Serial Port Fixup library is used by the
SPCR, DBG2 and SSDT Serial Port generator to describe
the serial port information in a definition block.

  +------------+   +------------+   +------------+
  |  SPCR Gen  |   |  DBG2 Gen  |   | SERIAL Gen |
  +------------+   +------------+   +------------+
        +----------------------------------+
        |  SSDT Serial Port Fixup library  |
        +----------------------------------+

The SSDT Serial Port Fixup library:
  - Parses the SSDT Serial Port template using the
    AmlLib library to generate an AML tree.
  - Updates the _UID, _HID and _CID values.
  - Fixes up the Serial port base address, length
    and the interrupt number in the _CRS descriptor.
  - Fixes up the serial-port name.
  - Serialises the AML Tree to a buffer containing
    the definition block data.
  The definition block data is then installed by the
  corresponding table generator.
