i2c: set hold time of SDA during transmit to an appropriate value (#273) 
* i2c: set hold time of SDA during transmit to 2 for TCS34725 color sensor

* i2c: fix issues in i2c_write_blocking_internal

* i2c: rename sda_hold_count to sda_tx_hold_count

* use assert rather than invalid_params_if for internal consistency checks

* i2c: use a more appropriate sda tx hold time at higher baudrates

* i2c: reduce 120/1e9 to the smallest possible integer numerator and denominator

* Don't use implicit 0 for field LSB

* 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
