ARM: dts: msm: move Focaltech touch node to SKUI's DTS

Focaltech touch controller is used only on SKUI targets and
not on SKUIC. However, SKUI's DT file is included in SKUIC DT
file which results in unnecessary inclusion of Focaltech's node
in SKUIC dtb. As a result, Focaltech driver's probe is
unnecessary invoked on SKUIC targets and increases boot up time
as well. This change moves Focaltech touch controller's DT node
to SKUI specific DT files only thereby decreasing the bootup
time on SKUIC.
