[ Upstream commit b8a83e600bdde93e7da41ea3204b2b3832a3c99b ]
Originally as it was defined the legacy bindings the pcie_inbound_axi and pcie_aux clock names were supposed to be used in the fsl,imx6sx-pcie and fsl,imx8mq-pcie devices respectively. But the bindings conversion has been incorrectly so now the fourth clock name is defined as "pcie_inbound_axi for imx6sx-pcie, pcie_aux for imx8mq-pcie", which is completely wrong. Let's fix that by conditionally apply the clock-names constraints based on the compatible string content.
