These always powered on power domains have typically not been described in the device tree. Because these power domains have been left out of the device tree there has not been any real need to properly describe the UART controllers power domain of Rockchip SoCs. On Rockchip RK3528 the UART controllers are spread out among the described PD_RKVENC, PD_VO and PD_VPU power domains. However, one UART controller belong to an undescribed always powered on power domain. Add support to describe an optional power-domains for the UART controllers.
