[U-Boot] [PATCH v2 1/2] rockchip: clk: rv1108: remove duplicate reset init

rockchip_reset_bind() already does the needed init for the reset
registers, only referenced the wrong cru structure.

So we can get rid of the open-coded reset init and just fix
the correct cru reference.

changes in v2:
- drop the now unused old softreset_reg struct
  softresets are only used inside the softreset driver and
  have their own separate struct
