Portenta H7: SPI, WIre, PWM, ADC, Video as wip
This is a replacement for PR: #71 and #82. All of the earlier commits were squashed into one. Then this was converted a few times during the #85 pr time frame as things kept changing and moving around. It has now been updated to the released .3 version. We defined the additional SPI ports and Wire ports. We defined an initial setup for Analog pins. Have similar hack to GIGA version for pure Analog. Added additional hacks for duplicated pins. That is two of the analog Pins are the exact same pin as some other digital pins... Added some PWM support. Also added WIP: camera support.
