[PATCH] Fix ADS7846 dependencies

Hi,

While playing with my kernel configuration, I found out that now,
setting CONFIG_HWMON to 'n' and TOUCHSCREEN_ADS7846 to 'y' was allowed,
which leads to a build failure.
This was caused by the commit 954423251daf362272076c6228dcdac65d72b287
which reverts the changes introduced by the commit
659cb49d6a8ba8d5651e53dd22a0addab6a479e6. 
This patch fix the trouble.
