parisc: Make struct parisc_driver::remove() return void

The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.

The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.

Also fold in a small checkpatch fix for:

WARNING: Unnecessary space before function pointer arguments
+	void (*remove) (struct parisc_device *dev);
