This is a follow-on to this thread[1] where we discussed the need to
support the vivaldi keyboard function row keys in the google hammer
driver. I've extracted the common code into a new vivaldi-keymap.c file
that can be used by the various keyboard drivers used on ChromeOS
devices to expose the function_row_physmap sysfs attribute. That's a
good place to keep the HID parsing logic for the vivaldi and hammer
keyboards too, so one function goes there for that as well. Finally, we
add support for the function row physmap attribute to the hammer driver.

Changes from v1 (https://lore.kernel.org/r/20220204202021.895426-1-swboyd@chromium.org):
 * Yet another new file for HID part to fix compilation problems

I see that this conversion broke stuff. I'll drop this patch and make it
a u32 and resend.
