[PATCH] hwmon: ltq-cputemp: restrict it to SOC_XWAY

[PATCH] hwmon: ltq-cputemp: restrict it to SOC_XWAY

[Randy Dunlap]

Building with SENSORS_LTQ_CPUTEMP=y with SOC_FALCON=y causes build
errors since FALCON does not support the same features as XWAY.

Change this symbol to depend on SOC_XWAY since that provides the
necessary interfaces.

Repairs these build errors:
