ENGR00216870-2:sdio:clock auto gating issue
For sdio device, clock should always keep on for some card.
so a private policy was added to exclude sdio case in sdhci_disable_clk.
but this policy is too tough. so block sdio's auto gating in
some case.For long term, this policy should be move up to host and
be optimized. For android,temporary optimize the policy and enable runtime
pm for sdio device can fix this bug.
