mmc: sdhci: Fix sdhci_led_control() path
The SDHC driver registers sdhci_led_control() with LED class device
and it gets invoked when the sysfs entry - /sys/class/leds/mmcX::
is updated. This function access SDHC Host control register (0x28)
and hence, check the driver state (runtime suspended/clocks gated)
before accessing it. Otherwise, it may result in unclocked access
resulting in system failure.
