description:
Finally fix problem discussed in this old thread:
http://mail-index.netbsd.org/tech-kern/2017/12/03/msg022661.html

Dell's radio hotkey sends a PMFE_RADIO_TOGGLE event, but nothing actually
listen to it.
Turn it into a PSWITCH_HK_WIRELESS_BUTTON hotkey, similar to
what thinkpad_acpi.c does.
Add type/subtypes seen on a Dell lattitude 5480 laptop.
XXX we need a PMFE_AUDIO_MICRO_TOGGLE, and something to handle it.
