stable inclusion from stable-5.10.52 commit 1479998d80279b332a7f90afafad80b2d3d4153e bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
