[PATCH v2 09/11] clk: qcom: ipq8074: add GP and Crypto clocks

[Abhishek Sahu <absahu-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

- It has 3 general purpose clock controller which supplies
  the clock in GPIO pins.
- It has Crypto Engine which has AXI, AHB and Core clocks.
  Other non APSS processors can also use Crypto Engine so
  these clocks are marked as VOTED clocks.
