Revert "mmc: sdhci-msm: Avoid enable SD card power if card is removed"

Browse source 
This reverts commit 82fc401559.
When there is no SD card inserted, this change causes the SD
card driver to wait for the mmc power IRQ that never comes.
As a result, the boot up time may be longer.
Revert this change and fix the original issue properly.
