HP41 TULIP4041 update

[MeindertKuipers]

Good news, TULIP4041 seems to be working on the Pico2 board. Only a few minor changes needed. Only real issue so far is that the FI line is not driven, meaning that I cannot test HP-IL. And I have done only limited functional testing so far. Really interesting is the power consumption which is supposedly better than the RP2040, probably next week.
Also important is that I do not seem to have any issues with the GPIO errata which is currently a hot item on the Pico forums.
