ENGR00125823-1 mxc esdhc: add a clock always on flag in plat_data
Add a control flag for clock always on function in plat_data.
By default ,esdhc clock will be automatically gate off by HW
if there's no CMD/DATA transferring.
This inferface allows user to easily disable clock auto gate off
according specicial using cases such as SDIO card that needs
clock to send SDIO interrupt signal to host.
