arm64/mm/ptdump: Add address markers for BPF regions
Kernel virtual region [BPF_JIT_REGION_START..BPF_JIT_REGION_END] is missing
from address_markers[], hence relevant page table entries are not displayed
with /sys/kernel/debug/kernel_page_tables. This adds those missing markers.
While here, also rename arch/arm64/mm/dump.c which sounds bit ambiguous, as
arch/arm64/mm/ptdump.c instead.
