x86, cpufeature: Rename X86_FEATURE_DTS to X86_FEATURE_DTHERM

commit 4ad33411308596f2f918603509729922a1ec4411 upstream.

It makes sense to label "Digital Thermal Sensor" as "DTS", but
unfortunately the string "dts" was already used for "Debug Store", and
/proc/cpuinfo is a user space ABI.

Therefore, rename this to "dtherm".

This conflict went into mainline via the hwmon tree without any x86
maintainer ack, and without any kind of hint in the subject.
