Subject: [PATCH] thermal: fix Kconfig dependencies

From: Heiko Carstens <heiko.carstens@...ibm.com>

git commit 3152fb9f11cdd2fd8688c2c5cb805e5c09b53dd9
"thermal: fix generic thermal I/F for hwmon" adds a select HWMON
to THERMAL. This causes HWMON to be selected regardless of its
other dependencies. In this case depends on HAS_IOMEM gets ignored
which causes this build error on s390:

drivers/hwmon/w83627hf.c: In function 'superio_outb':
drivers/hwmon/w83627hf.c:117: error: implicit declaration of function 'outb'

Change the select to a depends on to fix this. Should work as well.
