More work on enumerating cheap POS mice, arrrrgh.
...
Added timeout checks and retry functionality to control transaction
state machine. But some times the device just won't talk, so we flash
the fault LED slowly to give the user some clue about what happened.

Completed moving Upstream to interrupt-based SPI.
...
Although I am not entirely convinced this is necessary, as the SPI data
stall issue only appeared with optimisation off (-O0). Perhaps re-visit
this if Upstream needs more free CPU time later...

Added priority elevation to Downstream USB host processing code that
...
interacts with SPI.
It elevates to USB_OTG priority to avoid preemption by SPI, DMA, or USB
interrupts thus avoiding synchronisation issues between USB host stack
and SPI interface.
Also minor improvements to Downstream error handling.
