[PATCH 1/5] board: ti: j721e: Drop SERDES PHY init from board file

12 Jan 2024

Since commit 69b19ca67bcb ("arm: dts: k3-j721e: Sync with v6.6-rc1"),
the following error message is seen at u-boot
    "Sierra init failed:-19"
Probing and initializing the SERDES PHY from
board file is not a clean solution so drop it.
Proper use case should be via PHY_UCLASS APIs.
