arm64: dts: sun50i-a64-pinephone: Add AF8133J to PinePhone

New batches of PinePhones switched the magnetometer to AF8133J from
LIS3MDL because lack of ST components.

Both chips use the same PB1 pin, but in different modes.
LIS3MDL uses it as an gpio input to handle interrupt.
AF8133J uses it as an gpio output as a reset signal.

It wasn't possible at runtime to enable both device tree nodes and
detect supported sensor at probe time, because both drivers try to
acquire the same gpio in different modes.

Device tree fixup will be done in firmware without introducing new board
revision and new dts.
