mmc: core: Remove redundant mmc_power_up|off at runtime callbacks
Commit "mmc: core: Push common suspend|resume code into each bus_ops" moved the responsibility for doing mmc_power_up|off into each suspend/resume bus_ops. When using MMC_CAP_AGGRESSIVE_PM, through the runtime callbacks, calls to mmc_power_up|off became redundant. When removing them, we are also able to remove the calls to mmc_claim|release_host, thus simplifing code a bit more.
