[PATCH 0/3][FGH:linux-azure] Enforce CONFIG_ACPI_HOTPLUG_MEMORY annotation

[Impact]

These patches have no run time impact. There has recently been a request
to enable CONFIG_ACPI_HOTPLUG_MEMORY in focal:linux-kvm. I noticed
that all other cloud kernels have this config enabled except for
linux-azure, which MSFT specifically asked to have disabled. In an
effort to forestall homegenization of all cloud kernel settings, I've added
this annotation to remember why CONFIG_ACPI_HOTPLUG_MEMORY is not enabled.

[Test Plan]

cranky updateconfigs -c

[Where problems could occur]

There is no run time imaact.
