reset: reset-meson: add support for the Meson-S4 SoC Reset Controller

Compared to the A1 SoCs the number of RESET registers is different
and the offset for the level registers is the same. Add a new
compatible string and struct meson_reset_param to add support for the
reset controller on the S4 SoC.
