Subject: [PATCH 4.19 07/32] hwmon: (ltq-cputemp) restrict it to SOC_XWAY

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 151d6dcbed836270c6c240932da66f147950cbdb ]

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:

../drivers/hwmon/ltq-cputemp.c: In function 'ltq_cputemp_enable':
../drivers/hwmon/ltq-cputemp.c:23:9: error: implicit declaration of function 'ltq_cgu_w32'; did you mean 'ltq_ebu_w32'? [-Werror=implicit-function-declaration]
   23 |         ltq_cgu_w32(ltq_cgu_r32(CGU_GPHY1_CR) | CGU_TEMP_PD, CGU_GPHY1_CR);
../drivers/hwmon/ltq-cputemp.c:23:21: error: implicit declaration of function 'ltq_cgu_r32'; did you mean 'ltq_ebu_r32'? [-Werror=implicit-function-declaration]
   23 |         ltq_cgu_w32(ltq_cgu_r32(CGU_GPHY1_CR) | CGU_TEMP_PD, CGU_GPHY1_CR);
../drivers/hwmon/ltq-cputemp.c: In function 'ltq_cputemp_probe':
../drivers/hwmon/ltq-cputemp.c:92:31: error: 'SOC_TYPE_VR9_2' undeclared (first use in this function)
   92 |         if (ltq_soc_type() != SOC_TYPE_VR9_2)
