description:
- change major number limit for MI devices from 255 to 511,
  because twe is already using 332
- clarify that new MI devices should go to this file
  instead of majors.{ws,usb,std,tty,storage}
- fix major number conflict about hdmicec vs tty

OKed by matt@
the expression "previously not MI" is suggested by matt@ too.
