cpu/x86/lapic: Add Kconfig choice LAPIC_ACCESS_MODE
Allows compile-time optimisation on platforms that do not wish
to enable runtime checking of X2APIC.
Legacy lapic_cpu_init() is incompatible so there is dependency
on PARALLEL_MP. Also stop_this_cpu() is incompatible, so there
is dependency on !AP_IN_SIPI_WAIT.
Since the code actually lacks enablement of X2APIC (apparently
assuming the blob has done it) and the other small flaws pointed
out in earlier reviews, X2APIC_RUNTIME is not selected per
default on any platform yet.
