[PATCH] power: reset: rmobile-reset: Make sysc_base2 local

[Geert Uytterhoeven <geert+renesas@glider.be>]

The static global variable sysc_base2 is no longer used outside the
probe method and the reset handler, so it can be converted to a local
variable, and passed to the reset handler via its callback data.

Depends on commits 0867276eb12230a5 ("power: reset: rmobile-reset: Use
devm_platform_ioremap_resource() helper") and ba1188ea8be80a7b ("power:
reset: rmobile-reset: Use devm_register_sys_off_handler(RESTART)") in
battery/for-next (next-20240214 and later).
