Subject: [PATCH 2/3] dt-bindings: spi: Update clock-names property for ARM pl022

Below are the possibilities of pl022 clock-names property:
    - apb_pclk
    - [sspclk, SSPCLK, spiclk], apb_pclk

The current schema refers to second case and does not consider first
one. Hence, resolve the below dtc warnings by updating clock properties:

arch/arm64/boot/dts/lg/lg1313-ref.dt.yaml: spi@...00000: clock-names:0:
'apb_pclk' is not one of ['SSPCLK', 'sspclk']
    From schema: Documentation/devicetree/bindings/spi/spi-pl022.yaml
