feat(rcar): deduplicate plat_crash_print_regs

The plat_crash_print_regs code is functionally identical between
Renesas R-Car Gen3 and R-Car Gen4, deduplicate the code. Split
plat_crash_print_regs into plat_macros_cci.S and move the Gen3
specific plat_print_gic_regs macro into plat_macros_gic.S so it
can be pulled in only on R-Car Gen3.
