gpio: stp-xway: get rid of the #include <lantiq_soc.h> dependency

Browse source 
Use the xway_stp_{r,w}32 helpers in xway_stp_w32_mask instead of relying
on ltq_{r,w}32 from the architecture specific <lantiq_soc.h>.
This will allow the driver to be compile-tested on all architectures
that support MMIO.
