ARM: dts: qcom: msm8226: Add CPU frequency scaling support

Browse source

Add a node for the a7pll with its frequencies. With this we can use the
apcs-kpss-global driver for the apcs node and use the apcs to scale the
CPU frequency according to the opp-table.

At the same time unfortunately we need to provide the gcc node xo_board
instead of the XO via rpmcc since otherwise we'll have a circular
dependency between apcs, gcc and the rpm.
