cpu/x86/lapic: Support x86_64 and clean up code
Most LAPIC registers are 32bit, and thus the use of long is valid on
x86_32, however it doesn't work on x86_64.
* Don't use long as it is 64bit on x86_64, which breaks interrupts
in QEMU and thus SeaBIOS wouldn't time out the boot menu
* Get rid of unused defines
* Get rid of unused atomic xchg code
Tested on QEMU Q35 with x86_64 enabled: Interrupts work again.
Tested on QEMU Q35 with x86_32 enabled: Interrupts are still working.
Tested on Lenovo T410 with x86_64 enabled.
