msm: msm_sdcc: Add DDR support for eMMC/MMC

If eMMC/MMC cards supports DDR mode, MMC core
layer checks if host controller supports the DDR
mode or not and if host supports the DDR mode,
MMC core layer calls the set_ios to set the
DDR timing mode in host controller.

This change advertise that SDCC4 host controller
supports DDR mode timings and also sets DDR
timing mode when asked in set_ios.
