Subject: [PATCH 006/182] clocksource: qcom: split building of legacy vs
multiplatform support
The majority of the clocksource code for the Qualcomm platform is shared
between newer (multiplatform) and older platforms. However there is a bit
of code that isn't, so only build it for the appropriate config.
