[PATCH v2 0/3] RISC-V: ACPI: Update FADT and MADT versions

[Sunil V L]

Since RISC-V support is added only in ACPI 6.6, it should adhere to the
expected FADT and MADT versions. Update them.

Changes since v1:
	1) Updated code comments to reflect ACPI 6.6 chapter number.
	2) Added Michael's Ack.

[PATCH v2 2/3] hw/riscv/virt-acpi-build.c: Update FADT and MADT versions

[Sunil V L]

RISC-V support is added only in ACPI 6.6. According to the ACPI 6.6
specification, the minor version of the Fixed ACPI Description Table
(FADT) should be 6, and the Multiple APIC Description Table (MADT)
should use revision 7. So, update the RISC-V FADT and MADT to reflect
correct versions.

Update the code comments to reflect ACPI 6.6 version details.
