2021-12-15mb/google/corsola: move USB3 HUB reset funtion to bootblockRex-BC Chen
To save the S3 power, USB3_HUB_RST_L is externally pulled up to a weak resistor, so we have to reset the hub as early as possible. Otherwise the USB3 hub may be not usable. Therefore, move USB3 HUB reset function to bootblock.

1. Enable and setup USB drivers. 2. Pull up to a weak resistor for USB3_HUB_RST_L and we reset the hub via GPIO149.
