[PATCH v3 1/4] pmdomain: rockchip: propagate subdomain add errors

[Shawn Lin <shawn.lin@rock-chips.com>]

rockchip_pm_add_subdomain() ignored the return value of its recursive
call, so a failure deeper in the hierarchy was silently dropped and
probe still succeeded with an incomplete domain tree.

Fixes: 6be05b5ec161 ("soc: rockchip: power-domain: add support for sub-power domains")
