Use bus reset detection for all ARC OTG devices. Remove conflict from LV24020LP driver with some GPIO-by-number macros for PP502x. Start monitoring for USB stack once all core threads and queues are created otherwise queues will likely be registered after USB acks. Putting PP502x system_reboot in IRAM (unmapped, uncached) memory seems to help it work more consistently. Hopefully I got all the PP USB connect handlers in the right spot in irq_handler. If device seems unresponsive to cable, check there first.
