Impact: cleanup
x86_quirks->update_apic() calling looks crazy. so try to remove it:
1. every apic take wakeup_cpu member directly
2. separate es7000_apic to es7000_apic_cluster
3. use uv_wakeup_cpu directly

The ones which go only into struct genapic are de-inlined
by compiler anyway, so remove the inline specifier from them.
Afterwards, remove summit_setup_portio_remap completely as it
is unused.
Remove inline also from summit_cpu_mask_to_apicid, since it's
not worth it (it is used in struct genapic too).

Use BAD_APICID instead of 0xFF constants in summit_cpu_mask_to_apicid.
Also remove bogus comments about what we actually return.

Impact: cleanup
Make x86_quirks support more transparent. The highlevel
methods are now named:
extern void x86_quirk_pre_intr_init(void);
extern void x86_quirk_intr_init(void);
extern void x86_quirk_trap_init(void);
extern void x86_quirk_pre_time_init(void);
extern void x86_quirk_time_init(void);
This makes it clear that if some platform extension has to
do something here that it is considered ... weird, and is
discouraged.
Also remove arch_hooks.h and move it into setup.h (and other
header files where appropriate).

If BIOS hands over the control to OS in legacy xapic mode, select
legacy xapic related ops in the early apic probe and shift to x2apic
ops later in the boot sequence, only after enabling x2apic mode.
If BIOS hands over the control in x2apic mode, select x2apic related
ops in the early apic probe.
This fixes the early boot panic, where we were selecting x2apic ops,
while the cpu is still in legacy xapic mode.

Impact: build fix, cleanup
A couple of arch setup callbacks were mistakenly in apic_32.c, breaking
the build.
Also simplify the code a bit.

Move the 32-bit extended-arch APIC drivers to arch/x86/kernel/apic/
too, and rename apic_64.c to probe_64.c.

arch/x86/kernel/ is getting a bit crowded, and the APIC
drivers are scattered into various different files.
Move them to arch/x86/kernel/apic/*, and also remove
the 'gen' prefix from those which had it.
Also move APIC related functionality: the IO-APIC driver,
the NMI and the IPI code.
