MdePkg: MADT: Add Online capable flag in GICC
Bugzilla: 3706 'Code First - MADT GICC new flags'
On ARM systems physical CPU hotplug is not supported.
All CPUs are considered present and this is true
throughout the system uptime.
The ECR 2285 introduces a new 'online-capable' flag
in the GICC structure flags in ACPI 6.5, to signal
firmware policy (CPU is not enabled but it can be
enabled and onlined). This enables OSPM to support
virtual CPU hotplug (on virtual platforms for
instance).
This ECR also updates the MADT table revision to 6
to reflect the ACPI 6.5 changes. Therefore, update
the MADT table revision to match the value as
specified in ACPI 6.5.
