Mantas Pucka 56b99a5222 mmc: sdhci-msm: pervent access to suspended controller
commit f8def10f73 upstream.

Generic sdhci code registers LED device and uses host->runtime_suspended
flag to protect access to it. The sdhci-msm driver doesn't set this flag,
which causes a crash when LED is accessed while controller is runtime
suspended. Fix this by setting the flag correctly.
