PinePhone VBUS_CTRL fix

I found out about another hardware fix that should be done to my rev 1.2 and 1.2a PinePhones: 2020-10-12: Backlight changes when switching between USB-C power modes

The backlight level changes depending on whether you connect a USB-C device or not. This is a very minor thing, though I previously noticed it as well. The fix is said to be easy (removing a connection on the PCB), so we’ll see. I’ve already fixed the VCONN switches on my rev 1.1 and 1.2 PinePhones, so this shouldn’t be a problem.

Luckily the next batch of PinePhones will not be affected by this problem. Nice!

PinePhone is an amazing project and I love that it keeps on improving, thanks to the work of the community and PINE64 as well. Even though every iteration (batch sold) of the device is slightly better in terms of the hardware, the previous revisions are still supported, they work fine and often times they are even DYI fixable. I hope this continues to be a great success!
