83102f77ba Add a keymap putting Insert on the PrtSc key 
The lemp9 doesn't have an Insert key, but PrtSc is right there
next to Delete, and while I like taking screenshots, it really
doesn't deserve to be the primary function of a key.

Add an alternative keymap that makes the PrtSc key act as Insert,
leaving the print screen function on Fn+PrtSc

build with "make BOARD=system76/lemp9 KEYMAP=ins-prtsc"

a176da0ebe kbc: Handle setting typematic rate/delay 
Per [1], use a default delay of 500ms and a rate of 10.9 CPS. When the
Linux kernel starts, this will be updated by atkbd to the fastest
settings possible [2]: 250ms delay and 30 CPS.

Modifying these values with kbdrate to test settings will cause two
spurious ACKs in the kernel. This behavior is also present in the
proprietary firmware.
