spi: dt-bindings: apple,spi: Add t6020-spi compatible

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,spi" anymore [1]. Use
"apple,t8103-spi" as base compatible as it is the SoC the driver and
bindings were written for.

The SPI controller on Apple M2 Pro/Max/Ultra SoCs is compatible with
"apple,t8103-spi" so add its per-SoC compatible with the former as
fallback used by the existing driver.
