arm64: kdump: add VMCOREINFO's for user-space tools
In addition to common VMCOREINFO's defined in
crash_save_vmcoreinfo_init(), we need to know, for crash utility,
- kimage_voffset
- PHYS_OFFSET
to examine the contents of a dump file (/proc/vmcore) correctly
due to the introduction of KASLR (CONFIG_RANDOMIZE_BASE) in v4.6.
- VA_BITS
is also required for makedumpfile command.
arch_crash_save_vmcoreinfo() appends them to the dump file.
More VMCOREINFO's may be added later.
