According to ACPI spec, DefBuffer can take two parameters: BufferSize
and ByteList. Make it consistent with the spec. Uninitialized buffer
could be requested by passing ByteList as NULL to reserve space.

RSDT points to other tables FADT, MADT, GTDT. This code is shared with x86.
Here we still use RSDT as UEFI puts ACPI tables below 4G address space,
and UEFI ignore the RSDT or XSDT.

Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

* factor out ACPI const int packing out of build_append_value()
and rename build_append_value() to build_append_int_noprefix()
it will be reused for adding a plain integer value into AML.
will be used by is aml_processor() and CRS macro helpers
* extend build_append_int{_noprefix}() to support 64-bit values
it will be used PCI for generating 64bit _CRS entries
