[PATCH 23/30] rockchip: cpuinfo: Use sysreset_get_status() helper

[Jonas Karlman]

The get_reset_cause() helper only works on RK3288, RK3399, RK3568 and
RK3588 due to its dependency on rockchip_get_cru() and the glb_rst_st
field in struct rockchip_cru.

Convert to use the sysreset_get_status() helper now that the
sysreset_rockchip driver implements the get_status() ops to remove any
dependency on rockchip_get_cru() and the glb_rst_st field.
