soc: fsl: select FSL_GUTS driver for DPIO

stable inclusion
from stable-v5.10.144
commit c7f4c203d18ca29c437c405b2b1a8de5c2cac5d7
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0V7

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c7f4c203d18ca29c437c405b2b1a8de5c2cac5d7



--------------------------------

commit 9a472613 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: 51da14e9 ("soc: fsl: dpio: configure cache stashing destination")
