Some Wacom devices have keys with predefined meanings. However, when
support was originally added for these devices, the codes for these
keys were not available yet. These keys were thus reported with
the numbered KEY_PROG* range.
Some missing key codes were added with commit 4eb220cb35a9 ("HID:
wacom: generic: add 3 tablet touch keys") and we are now able to
report the proper key codes. We continue to report the original
KEY_PROG codes so as not to break any unknown applications that
may depend on them.
Also, to support the touch key, track its state in the pad report.

note I left off the DTK wrench key because it reports a BTN code instead of a KEY code |
The EKR ring claims a range of 0 to 71 but actually reports
values 1 to 72. The ring is used in relative mode so this
change should not affect users.
