[FR] Multi-drive, USB support for Power Loss Recovery

[alvarotorijano]

Did you test the latest bugfix-2.0.x code?

No, but I will test it now!

Bug Description

Power loss recovery seems not to work over USB drives. Tested on MKS Robin Nano v3.
I've tested the PLR with only SD support and works great. Then enabled USB support and does not works with any configuration (USB_FLASH_DRIVE_SUPPORT + USE_UHS2_USB / USE_UHS3_USB / NONE and or USE_OTG_USB_HOST and any possible combination) Also tried with MULTI_VOLUME with no results.
File created on USB seems to be correct but it is not readen because USB seems to be mounted too late to be detected on power on secuence.
Is there anything that I'm missing?
