iio: st_pressure: st_accel: Fix initialization of platform_data

Commit 7383d44b added a pointer pdata which gets initialized with the default platform_data when non was defined. But it did not pass this pointer to the st_sensors_init_sensor call but still used the maybe uninitialized platform_data from dev.

This breaks initialization when no platform_data is given and the optional st,drdy-int-pin devicetree option is not set.

As pdata was not used at all after this a subsequent commit removed the setting of pdata. As it is needed to fix this the first patch reverts that commit.

pdata"
