ARM: pxa/raumfeld: use PROPERTY_ENTRY_INTEGER to define props

gcc-6.0 notices that the use of the property_entry in this file that
was recently introduced cannot work right, as we initialize the wrong
field:

raumfeld.c:387:3: error: the address of 'raumfeld_rotary_encoder_steps' will always evaluate as 'true' [-Werror=address]
   DEV_PROP_U32, 1, &raumfeld_rotary_encoder_steps, },
   ^~~~~~~~~~~~
raumfeld.c:389:3: error: the address of 'raumfeld_rotary_encoder_axis' will always evaluate as 'true' [-Werror=address]
   DEV_PROP_U32, 1, &raumfeld_rotary_encoder_axis, },
   ^~~~~~~~~~~~
raumfeld.c:391:3: error: the address of 'raumfeld_rotary_encoder_relative_axis' will always evaluate as 'true' [-Werror=address]
   DEV_PROP_U32, 1, &raumfeld_rotary_encoder_relative_axis, },
   ^~~~~~~~~~~~

The problem appears to stem from relying on an old definition of
'struct property', but it has changed several times since the code
could have last been correct.

This changes the code to use the PROPERTY_ENTRY_INTEGER() macro instead,
which works fine for the current definition and is a safer way of doing
the initialization.
