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

[Kuldeep Singh <singh.kuldeep87k@xxxxxxxxx>]

Pl022 clock-names can be one of following:
['apb_pclk'] or ['sspclk', 'apb_pclk']

The current schema refers to second case only. Make necessary changes to
incorporate both the cases and resolve below dtc warnings:
clock-names: 'apb_pclk' is not one of ['sspclk']
