uvesafb: improve parameter handling.
1) Now module_param(..., invbool, ...) requires a bool, and similarly
module_param(..., bool, ...) allows it, change pmi_setpal to a bool.
2) #define param_get_scroll to NULL, since it can never be called (perm
argument to module_param_named is 0).
3) Return -EINVAL from param_set_scroll if the value is bad, so it's
reported.
Note that I don't think the old fb_get_options() is required for new
drivers: the parameters automatically work as uvesafb.XXX=... anyway.
