The sdhci-msm driver supports the device in both RUNNING
and IDLE states, when eMMC/SD are not reading or writing,
eMMC/SD are in IDLE state, the power management module
will suspend the device(power off and reduce frequency,
etc.), putting the device into a low-power mode. But the
current sdhci-msm driver cannot put device enter into
low-power mode.

Enable aggressive PM capability to support runtime PM
functionality, allowing the eMMC/SD card to enter
lowe-power mode.
