Subject: [PATCH 0/2] J722S: Disable WIZ0 and WIZ1 in SoC file

Hello,

This series disables the "serdes_wiz0" and "serdes_wiz1" device-tree
nodes in the J722S SoC file and enables them in the board files where
they are required along with "serdes0" and "serdes1". There are two
reasons behind this change:
1. To follow the existing convention of disabling nodes in the SoC file
   and enabling them in the board file as required.
2. To address situations where a board file hasn't explicitly disabled
   "serdes_wiz0" and "serdes_wiz1" (example: am67a-beagley-ai.dts)
   as a result of which booting the board displays the following errors:
     wiz bus@...00:phy@...0000: probe with driver wiz failed with error -12
     ...
     wiz bus@...00:phy@...0000: probe with driver wiz failed with error -12

Series is based on linux-next tagged next-20250408.

Regards,
Siddharth.
