Subject: [PATCH v5 4/6] phy: dt-bindings: cdns,dphy: make clocks optional for Rx mode

The clocks are not used by the DPHY when used in Rx mode so make them
optional for it by using a conditional based on compatible.

Signed-off-by: Pratyush Yadav <p.yadav@...com>

Changes in v5:
- Make clocks a required property based on the compatible.

Changes in v3:
- Add Rob's Ack.

Changes in v2:
- Re-order subject prefixes.
