Subject: [PATCH] ARM: dts: socfpga: remove syscon compatible string for sysmgr node

From: Niravkumar L Rabara <niravkumar.l.rabara@...el.com>

The SoCFPGA System Manager(sysmgr) dt bindings do not use the syscon
compitible, nor does the Linux system manager driver rely on it.
Remove "syscon" for Arria5, Arria10 and Cyclon5 sysmgr node and fixed
dtbs_check warnings like:

socfpga_arria5_socdk.dtb: sysmgr@...08000: compatible: 'oneOf' conditional failed, one must be fixed:
   ['altr,sys-mgr', 'syscon'] is too long
   'altr,sys-mgr-s10' was expected
   'altr,sys-mgr' was expected
   from schema $id: http://devicetree.org/schemas/soc/altera/altr,sys-mgr.yaml#

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202501102323.Xnte2yhi-lkp@intel.com/
