drivers: nxp_s32: add missing soc.h inclusion

Some NXP S32 shim drivers are using macros defined in
soc/arm/nxp_s32/*/soc.h but not including soc.h. Those still
can be built because the header file is included indirectly
by some other header files. This is very fragile, it should
be included directly
