mmc: dw_mmc-rockchip: Fix runtime PM support for internal phase support
[ Upstream commit 6465a8bbb0f6ad98aeb66dc9ea19c32c193a610b ]
RK3576 is the first platform to introduce internal phase support, and
subsequent platforms are expected to adopt a similar design. In this
architecture, runtime suspend powers off the attached power domain, which
resets registers, including vendor-specific ones such as SDMMC_TIMING_CON0,
SDMMC_TIMING_CON1, and SDMMC_MISC_CON. These registers must be saved and
restored, a requirement that falls outside the scope of the dw_mmc core.
