mmc: core: Add DT bindings for SD card's UHS bus speed modes
Provide the option to configure these speed modes per host, for those host driver's that can't distinguish this in runtime. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Chris Ball <chris@printf.net>
