Revert "mmc: core: wait while adding MMC host to ensure root mounts successfully"
This reverts commit 3500ed90b26a9935b943b5e2e4cd3226600d6b58.
The reverted patch caused a significant performance regression when
booting with the root file system on eMMC.
Before the patch:
[ 1.625623] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.
After the patch:
[ 1.935851] VFS: Mounted root (ext4 filesystem) readonly on device 179:2.
That was an addition of 310 ms which is a 19% performance degradation.
