Subject: [PATCH V2 2/2] clk: qcom: Put venus core0/1 gdscs to hw control mode

The venus video ip's internal core blocks are under the
control of the firmware and their powerdomains needs to be
'ON' only when used by the firmware. So putting it into
hw controlled mode lets this to happen, otherwise the firmware
hangs checking for this.
