Subject: [PATCH] ARM: dts: NSP: MX65: add qca8k falling-edge, PLL properties

This patch enables two properties for the QCA8337 switches on the MX65.

Set the SGMII transmit clock to falling edge
"qca,sgmii-txclk-falling-edge" to conform to the OEM configuration [1].

The new explicit PLL enable option "qca,sgmii-enable-pll" is required
[2].
