[PATCH v3] arm64: dts: imx8mp-venice-gw74xx: update to revB PCB

From: Tim Harvey
Date: Fri Jun 09 2023 - 15:52:44 EST

Update the imx8mp-venice-gw74xx for revB:
- add CAN1
- add TIS-TPM on SPI2
- add FAN controller
- fix PMIC I2C bus (revA PMIC I2C was non-functional so no need for
backward compatible option)
- M2 socket GPIO's moved

Signed-off-by: Tim Harvey <tharvey@xxxxxxxxxxxxx>
---
v3:
- add missing address-cells and size-cells to gsc node causing
dtbs_check warnings

v2:
- fix fan-controller unit-address
