only NUMAQ uses this quirk: to prevent the timer IRQ from being added
on secondary nodes.
All other genapic templates can have a NULL ->multi_timer_check()
callback.
Also, extend the generic code to treat a NULL pointer accordingly.

Impact: cleanup
The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in
a rather nasty way by re-defining it to zero. That is infinitely
fragile and makes it very hard to see what to code really does in
a given context. The very same constant has different meanings and
values - depending on which subarch is enabled.
Untangle this mess by never undefining the constant, but instead
propagating the right values into the genapic driver templates.

the ->ESR_DISABLE shouting variant was used to enable the esr_disable
macro wrappers. Those ugly macros are removed now so we can rename
->ESR_DISABLE to ->disable_esr

Impact: cleanup
Most subarchitectures want to disable the APIC ESR (Error Status Register),
because they generally have hardware hacks that wrap standard CPUs into
a bigger system and hence the APIC bus is quite non-standard and weirdnesses
(lockups) have been seen with ESR reporting.
Remove the esr_disable macros and put the desired flag into each
subarchitecture's genapic template directly.

Clean up all the target_cpus() namespace overlap that exists
between bigsmp, es7000, mach-default, numaq and summit - by
separating the different functions into different names.

Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE.
The typical 32-bit and the 64-bit build all dereference via the genapic,
so it's pointless to hide that indirection via these ugly macros.
Furthermore, it also obscures subarchitecture details.
So replace it with apic->irq_dest_mode / etc. accesses.

int_delivery_mode is supposed to mean 'interrupt delivery mode', but
it's quite a misnomer as 'int' we usually think of as an integer type ...
The standard naming for such attributes is 'irq' - so rename the following
fields and macros:
int_delivery_mode => irq_delivery_mode
INT_DELIVERY_MODE => IRQ_DELIVERY_MODE
int_dest_mode => irq_dest_mode
INT_DEST_MODE => IRQ_DEST_MODE

x86 subarchitectures each defined a "apic_id_registered()" method,
which could be an inline function depending on which subarch we build
for, and which was also the name of a genapic field.
Untangle this namespace spaghetti by giving each of the instances
a separate name.
Also remove wrapper macro obfuscation.

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.

The APIC_INIT() / APICFUNC / IPIFUNC macros were ugly and obfuscated
the true identity of various APIC driver methods.
Now that they are not used anymore, remove them.

Clean up the APIC driver template:
- order fields properly
- use the macro names explicitly (so that they can be renamed later)
- fill in NULL entries as well

Rename genapic-> to apic-> references because in a future chagne we'll
