Cache Control during mmc_suspend_host

[Saugata Das]

Hi Seungwon Jeon

I see a small issue with the implementation mmc_suspend_host,

int mmc_suspend_host(struct mmc_host *host)
{
.....
        err = mmc_cache_ctrl(host, 0);
}

So, within mmc_suspend_host we are disabling the cache. But I do not
see a corresponding enabling of cache within mmc_resume_host. I
suggest we have either enabling of cache within mmc_resume_host or
within mmc_suspend_host, we replace mmc_cache_ctrl(host, 0) with the
flush operation, mmc_flush_cache(host->card).
