Input: stmfts - use async probe & suspend/resume to avoid 2s delay
Executing stmfts_power_on() function lasts over 2 seconds, what significantly slows down the boot and resume processes if driver is compiled in. Avoid this delay by forcing this driver to be probed and suspended/resumed asynchronously.
