Set fan max speed to kick in at 65*C. This keeps the unit roughly
at 70*C or lower, when pusing all cores for an extended period of
time.

Fan, RTC and USB support
RTC requires rtc pcf85063 driver
Fan requires hwmon emc2305 driver
Added wakeup-source to fanctrl node so emc2305 module loads at boot.

BPI-CM4: Add support for the waveshare cm4-io-base-b

BPI-CM4: Enable usb support on waveshare baseboards via overlay
BPI-SM1: Removed UART_B overlay. Short of it being an available
option in the vendor kernel via overlay. I can not find any docs
to support why that is. I feel it is safer that we just remove it.
BPI-SM1: Add UART_A "pin-ctrl: cts rts"
