[PATCH 5.13 313/351] arm64: dts: ti: k3-j721e-main: Fix external refclk input to SERDES

From: Kishon Vijay Abraham I <kishon@ti.com>

[ Upstream commit 5c6d0b55b46aeb91355e6a9616decf50a3778c91 ]

Rename the external refclk inputs to the SERDES from
dummy_cmn_refclk/dummy_cmn_refclk1 to cmn_refclk/cmn_refclk1
respectively. Also move the external refclk DT nodes outside the
cbass_main DT node. Since in j721e common processor board, only the
cmn_refclk1 is connected to 100MHz clock, fix the clock frequency.

Fixes: afd094ebe69f ("arm64: dts: ti: k3-j721e-main: Add WIZ and SERDES PHY nodes")
