Remove remaining bits of the subarchitecture code. Now that all the
special platforms are runtime probed and runtime handled, we can remove
these facilities.

Spread mach_apic.h definitions into genapic.h. (with some knock-on effects
on smp.h and apic.h.)

Impact: cleanup
- allow NULL ->mps_oem_check() entries
- clean up the code flow

Impact: refactor code
x86 subarchitectures each defined a "acpi_madt_oem_check()" method,
which could be an inline function, or an extern, or a static function,
and which was also the name of a genapic field.
Untangle this namespace spaghetti by setting ->acpi_madt_oem_check()
to NULL on those subarchitectures that have no detection quirks,
and rename the other ones (summit, es7000) that do.
Also change default_acpi_madt_oem_check() to handle NULL entries,
and clean its control flow up as well.

Rename genapic-> to apic-> references because in a future chagne we'll
open-code all the indirect calls (instead of obscuring them via macros),
so we want this reference to be as short as possible.

Impact: cleanup, solve 80 columns wrap problems
mp_config_table should be renamed to mpc_table.
The reason: the 'c' in MPC already means 'config' -
no need to repeat that in the type name.

Impact: fix boot crash on 32-bit
Hiroshi Shimamoto reported a boot failure on 32-bit x86.
The setting of x86_quirks.wakeup_cpu is missing (when
not passing in an explicit apic= boot parameter).

Impact: fix wakeup_secondary_cpu with hotplug
We can not put that into x86_quirks, because that is __initdata.
So try to move that to genapic, and add update_genapic in x86_quirks.
later we even could use that stub to:
1. autodetect CONFIG_ES7000_CLUSTERED_APIC
2. more correct inquire_remote_apic with apic_verbosity setting.

... so it could fall back to normal numa and we'd reduce the impact of the
NUMAQ subarch.
NUMAQ depends on GENERICARCH
also decouple genericarch numa from acpi.
also make it fall back to bigsmp if apicid > 8.
