Subject: [PATCH] refactor: guard multiboot2.h include in pmm.c with #if x86

multiboot2.h is an x86/GRUB boot protocol header. pmm.c (generic
mm/ code) included it unconditionally even though all Multiboot2
usage is already inside #if x86 blocks. Guard the include so it
is not pulled in on ARM/RISC-V/MIPS builds.

Passes: make, cppcheck, QEMU smoke test.
