Synchronize Linux 6.1 configuration with RPi4

[fhunleth]

This is a work in progress to fix the Linux configuration 6.1 on the RPi3.

• Sync Linux config to RPi4
• Trim more
• Trim even more
• Trim even more
• Trim even more
• Enable pstore pmsg and panic_timeout

I have this booted on an rpi3. I see some bluetooth errors but unsure if that was happening before
