[PATCH v3 10/13] dt-bindings: spi: atmel-quadspi: make "pclk" mandatory

[<Tudor.Ambarus@xxxxxxxxxxxxx>]

From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

Naming clocks is a good practice. Make "pclk" madatory even if
we support unnamed clock in the driver, to be backward compatible
with old DTs.
