reset: reset-meson: Add support for Amlogic T7 SoC reset controller

Browse Source 
There are 7 sets of Reset Source in Amlogic T7 SoC reset controller,
and the offset between base and level registers is 0x40.
Add a new compatible string and struct meson_reset_param to support
the reset controller on T7 SoC.
