arm64: show_regs: Dump the LRs HW values

These were dropped in [1], after relocation, for their values offset by
reloc_off.
Unconditionally show the HW values and add a '(reloc)' hint for the
offset values showed after relocation.
Also, the LRs' dumps are now formatted the same way the other regs' are.
