This was pointed out with the recent name change of or32_early_setup to
or1k_early_setup. Investigating the file I found a few other warnings
so cleaning them up here.

Fix this the missing or1k_early_setup prototype warning by adding an
asm/setup.h file to define the prototype.
arch/openrisc/kernel/setup.c:246:13: warning: no previous prototype for 'detect_unit_config' [-Wmissing-prototypes]
246 | void __init detect_unit_config(unsigned long upr, unsigned long mask,
| ^~~~~~~~~~~~~~~~~~
The function detect_unit_config is not used, just remove it.
arch/openrisc/kernel/setup.c:221: warning: Function parameter or member 'fdt' not described in 'or1k_early_setup'
Add @fdt docs to the function comment to suppress this warning.
