Phil Howard 5510c82564 PicoDisplay: Fix rotation offset for #562. 
Pico Display would have a pixel offset at 90 and 180 degree rotations.

Add a special case offset tweak for these, and demystify the rotate_180 variable.

Phil Howard 8cf276b992 inky73: Add busy wait timeout. 
Add a timeout to fix Inky 7.3" hanging on batteries.

Basically assumes the update has finished if it takes > 45s, and allows a subsequent attempt
rather than hanging indefinitely.

Raised, texted and fixed by w3stbam: https://github.com/pimoroni/pimoroni-pico/pull/900

Rewritten as mentioned in the PR.

Phil Howard b0d53dadb3 Hub75: avoid clobbering shared IRQ handlers. 
MicroPython's DMA class uses shared IRQ handlers, which would be
clobbered by Hub75's use of an exclusive handler.

Additionally clean up some dead code (DMA_IRQ_1??), more epxlicitly
clean up the claimed PIOs and programs, and do not use a fixed
DMA channel. This seems to have fixed a bug whereupon Hub75 would
hardlock on the 5th soft reset.

Phil Howard c19b2276f1 st7789: Remove mystery meat command implicated by #567.

Phil Howard 70a1b26041 ADC: Avoid re-initialising ADC. 
Only init the ADC if it's not already running.

In MicroPython this could trounce an already initialised and configured ADC,
and would disable the temperature sensor if it had been enabled by a user
before initialising any of the affected libraries.

Phil Howard 652de85f4d Tufty 2040: RGB565 DMA display update. 
Use DMA to transfer a native RGB565 display buffer to PIO rather than pushing into the TX FIFO in a loop.
