* making pio_calculate_clkdiv8_from_float round to the neareset 1/256 (not lower 1/256)
* chage rounding of all float clkdivs to round to neareset; default to nearest (which is a backwards incompatible change, but I think OK), and add ability to turn it off
* fix copy/paste errors in PICO_CONFIG
* Calculate size of FRAC field using its own MSB and LSB, rather than hoping that INT_LSB is in the right place
* Add a new REG_FIELD_WIDTH macro, and make the calculation of the clock-dividers more consistent

* Use consistent capitalisation for 'GitHub'
* Small typos and markup errors
* Board definition header files for the iniital set of SparkFun rp2040 boards

Fixup SparkFun headers
* Pimoroni board headers
* Add LED related board defines PICO_CONFIGs (to pico_stdlib for now)
* more board config changes
* add Adafruit feather, itsybitsy, qtpy board headers
* add PICO_DEFAULT_WS2812_POWER_PIN define
* MOSI/MISO -> TX/RX, some UART cleanup.. make vgaboard.h defines take preference over pico.h ones
* local change to tinyusb to cope with no default LED or UART
* fix review issues

In C, func() is a function taking an unspecified number of arguments,
vs func(void) a function taking no arguments. In C++ both forms indicate
"no arguments."
Update these headers to use the (void) form, which is correct in both
languages and avoids complaints when -Wstrict-prototypes is specified.
