Dinh Nguyen 42918d28cb dt-bindings: altera: document syscon as fallback for sys-mgr
For 32-bit Altera SoCFPGA parts, the sys-mgr uses the syscon as a fallback.

This change addresses this warning from dtbs_check:

sysmgr@ffd08000 (altr,sys-mgr): 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
