Added 2x USB-A ports and a few other things

I Used a reliable USB2514B chip as my USB hub to add two USB ports with safe current-limiting TPS2051B chips by texas instruments

I also added a high-speed MUX circuit using the TS3USB221A chip, so now there will be a physical switch to change between chip flashing mode via USB-C and normal USB-A host operation.

• Also fixed the Compute Module’s power input
• Did a few other things that my sleep-deprived ahh can’t remember

What’s Next:

Adding a 7” Touchscreen to the handheld!
