[PATCH edk2-platforms v1 0/3][platforms/devel-dynamictables] Update for ACPICA compiler enhancements

[Sami Mujawar]

The ACPICA iAsl compiler has recently been enhanced to support a
feature required by Dynamic Tables Framework for processing ASL
files. The compiler however generates slightly different symbol
names to what was previously referenced in the Configuration Manager.

This patchset adapts to the latest iASL compiler options.

[PATCH edk2-platforms v1 1/3][platforms/devel-dynamictables] Platform/ARM: Match asl compiler output for Juno

[Sami Mujawar]

The iASL compiler's -tc option has been updated to generate
output that is suitable for including from a C file. The iASL
compiler uniquely names the C array containing the processed
table data as <ASL filename>_aml_code. This update can be seen
in the ACPICA git repository at
https://github.com/acpica/acpica/commit/f9a88a4c1cd020b6a5475d63b29626852a0b5f37

A corresponding change is required in the ConfigurationManager
and this patch contains the necessary changes to adapt to the
generated iASL compiler output.

For both 1-2/3, please add a date here, like in the Readme.md.

[PATCH edk2-platforms v1 3/3][platforms/devel-dynamictables] Update Readme.md to reflect ACPICA compiler update

[Sami Mujawar]

The ACPICA iASL compiler has been enhanced to support the
generation of an AML hex file which is required by the
Dynamic Tables Framework. The patch for this enhancement
has been integrated in the ACPICA repository. Therefore
the Prerequisites section in the Readme has been updated
accordingly.

Linux distributions tend to use dates to refer to what particular
point a version is based on, since snapshot updates are frequently
necessary.

In this case, that is 16 March 2018 - please mention that as well in
the message.

[[Evan Lloyd]] Whilst agreeing that a date would be helpful, I don't think that Linux usage is relevant.  EDK II seems to go to some lengths to avoid Linux usage (e.g. CR LF).

[[Evan Lloyd]] Given the international nature of edk2-devel, I suggest there is a strong case for adopting ISO-8601 date format, so I'd prefer 2018-03-16.

Linux distributions are consumers of edk2 code in the form of
packaged builds of ArmVirtPkg and OvmfPkg.
