[PORT_FROM_R2]mmc: panic: using the api provided by PMU driver in panic mode

BZ: 21728

To power up host controller in panic mode, pci_set_power_state() is not
suitable since it will cause schedule in panic mode.

PMU driver has provided an API named pmu_set_lss01_to_d0i0_atomic which
is for lss01 device only to put it in D0i0 mode, and it can only be used
in atomic context.
