openrisc: Fix compiler warnings in setup
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. arch/openrisc/kernel/setup.c:220:13: warning: no previous prototype for 'or1k_early_setup' [-Wmissing-prototypes] 220 | void __init or1k_early_setup(void *fdt) | ^~~~~~~~~~~~~~~~ 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.
