The Share button, if present, is always one of two offsets from the end of the
file, depending on the presence of a specific interface. As we lack parsing for
the identify packet we can't automatically determine the presence of that
interface, but we can hardcode which of these offsets is correct for a given
controller.

More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the
future, but for now I only added the ones that I have the ability to test
directly.

Two controllers -- Mad Catz JOYTECH NEO SE Advanced and PDP Mirror's
Edge Official -- were missing the value of the mapping field, and thus
wouldn't detect properly.

All of these cases are perfectly valid and good traditional C, but hit
by the "you're not NUL-terminating your byte array" warning.

And none of the cases want any terminating NUL character.

Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974
magnetometer driver, I just removed the explicit array size and let gcc
expand the 3-byte and 6-byte arrays by one extra byte, because it was
the simpler change).

GCC 15's new -Wunterminated-string-initialization notices that the
16 character lookup table "nibbles" (which is not used as a C-String)
needs to be marked as "nonstring":

drivers/input/joystick/magellan.c: In function 'magellan_crunch_nibbles':
drivers/input/joystick/magellan.c:51:44: warning: initializer-string for array of 'unsigned char' truncates NUL terminator but destination lacks 'nonstring' attribute (17 chars into 16 available) [-Wunterminated-string-initialization]
   51 |         static unsigned char nibbles[16] = "0AB3D56GH9:K<MN?";
      |                                            ^~~~~~~~~~~~~~~~~~

Add the annotation and While at it, mark the table as const too.
