Subject: [PATCH v2 7/7] clk: qcom: Add SDX65 APCS clock controller support

Add a driver config support for the SDX65 APCS clock controller. It is part
of the APCS hardware block, which among other things implements a combined
mux and half integer divider functionality. The APCS clock controller has 3
parent clocks:

1. Board XO
2. Fixed rate GPLL0
3. A7 PLL

This is required for enabling CPU frequency scaling on SDX65-based
platforms.
