…h size Add a new HAVE_LIMITED_CODE_SIZE symbol that enables a menu to select optional features. This symbol is enabled on chips with small build sizes. Replace the HAVE_GPIO_BITBANGING with four new symbols: WANT_GPIO_BITBANGING, WANT_DISPLAYS, WANT_SENSORS, WANT_SOFTWARE_SPI, and WANT_SOFTWARE_I2C. This allows users a little more flexibility when selecting features they need. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

way better than my quick fix |

Tested with stm32f042x6 in Voron V0 display and works great. |

@KevinOConnor Can you add also atmega328p and similar? Maybe also options like:

I committed this PR.
We can certainly add additional chips and additional options. I'd like to commit this first and look to add additional features later. Cheers, |

Add a new "optional features" menu to "make menuconfig" for chips with limited code size (the atmega168, ar100, stm32f031, stm32f042, and pru). This menu allows a user to select optional code features (bitbanging support, display support, sensor support, software spi, and software i2c).
This fixes the build for the stm32f042, in that it allows users to disable software i2c support (or some other feature) to make the build fit within the chip flash again.
