c2465f95c4 ACPI: Enable FPDT on arm64
FPDT provides some boot timing records useful for analyzing
parts of the UEFI boot stack. Given the existing code works
on arm64, and allows reading the values without utilizing
/dev/mem it seems like a good idea to turn it on.

e14a371f73 Documentation: arm64/acpi : clarify arm64 support of IBFT
In commit 94bccc3407 ("iscsi_ibft: make ISCSI_IBFT dependson ACPI instead
of ISCSI_IBFT_FIND") Kconfig was disentangled to make ISCSI_IBFT selection
not depend on x86.

Update arm64 acpi documentation, changing IBFT support status from
"Not Supported" to "Optional".
Opportunistically re-flow paragraph for changed lines.

b693d0b372 docs: arm64: convert docs to ReST and rename to .rst
The documentation is in a format that is very close to ReST format.

The conversion is actually:
  - add blank lines in order to identify paragraphs;
  - fixing tables markups;
  - adding some lists markups;
  - marking literal blocks;
  - adjust some title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
