[PATCH 2/2] board: ti: j721e: evm.c: Fix the probing of in Sierra SerDes0

[Aswath Govindraju]

Initialization and power on operations of links have been moved under the
link device in the Sierra SerDes driver. Also, the UCLASS of
sierra_phy_provider has been changed to UCLASS_MISC.

Therefore, fix the probing of SerDes0 instance accordingly.
