soc: fsl: select FSL_GUTS driver for DPIO

Browse Source 
commit 9a472613f5 upstream.

The soc/fsl/dpio driver will perform a soc_device_match()
to determine the optimal cache settings for a given CPU core.

If FSL_GUTS is not enabled, this search will fail and
the driver will not configure cache stashing for the given
DPIO, and a string of "unknown SoC" messages will appear:

fsl_mc_dpio dpio.7: unknown SoC version
fsl_mc_dpio dpio.6: unknown SoC version
fsl_mc_dpio dpio.5: unknown SoC version

Fixes: 51da14e96e ("soc: fsl: dpio: configure cache stashing destination")
