ARM: dts: msm: Specify clocks and regulators for venus

Define each clock and regulator that's used by the venus/vidc
driver.

APQ8084 adds two new power domains, which are regulated by
venus-core0-supply and venus-core1-supply respectively. In
addition, include the "core0_clk" and "core1_clk" so that the
driver can enable it.  Within venus core0 refers to the HEVC
decode core whereas core1 refers to the core for legacy codecs.
