… just yet - CPU freq needs to be 120 Mhz - CFG_TUSB_OS should be PICO for multiple core spinlock - add check for tud/tuh task with OS NONE & OS PICO - core1 should wait for core0 initialize usbh before calling SOF. - may not reset VBUS power pin ?

@tannewt This PR get USB host running but this MPU code need to be commented out. It is probably due to some code not entirely in RAM (or still ROM access e.g const data). I guess this already made some progress for you to work on.
