raspberypi: Allow mpconfigboard to override additional items 

This allows more options to be overridden to 0 in an mpconfigboard.mk.

Improved:
 * FRAMEBUFFERIO, FULL_BUILD, BITOPS, PWMIO, RGBMATRIX, OTARYIO, PULSEIO, WATCHDOG

Still problematic (pull requests welcome):
 * RP2PIO & NEOPIXEL_WRITE, possibly only if a status neopixel is defined
 * BITBANGIO, possibly only if BUSIO is enabled
 * RTC

Incidentally, with RP2PIO & NEOPIXEL_WRITE, BITBANGIO, and RTC re-enabled I get
```
323956 bytes used, 720524 bytes free in flash firmware space out of 1044480 bytes (1020.0kB).
12072 bytes used, 250072 bytes free in ram for stack and heap out of 262144 bytes (256.0kB).
```

Closes #4515
