Sean Cross 296ba101ec nrf: set WDT priority to 2
The previous setting of `1` meant that the bluetooth system couldn't be
used when the watchdog timer was enabled.

Sean Cross 589cb1af6d nrf: watchdog: use nrfx_wdt driver
Instead of directly poking registers, use `nrfx_wdt`.

Sean Cross 370fc7293a nrf: support disabling SPIM3
SPIM3 is faster than all other SPI blocks, and is capable of generating
a 32 MHz clock.  However, it cannot be used at the same time as the BLE
radio without dedicating an additional 8 kB of RAM to it.

Therefore, some boards may want to disable this.  Support pre-defining
NRFX_SPIM3_ENABLED on the command line to disable it on some bords.

Sean Cross 3ed5b87b8f nrf: add support for nrf52833
This adds preliminary support for the nRF52833, which is a variant of
the nRF52840 with half the RAM, half the flash, and fewer peripherals.

Move atmel-samd to tinyusb and support nRF flash.
This started while adding USB MIDI support (and descriptor support is
in this change.) When seeing that I'd have to implement the MIDI class
logic twice, once for atmel-samd and once for nrf, I decided to refactor
the USB stack so its shared across ports. This has led to a number of
changes that remove items from the ports folder and move them into
supervisor.

Furthermore, we had external SPI flash support for nrf pending so I
factored out the connection between the usb stack and the flash API as
well. This PR also includes the QSPI support for nRF.
