Add power sequence for vpu4 by reusing from previous generation wherever
possible. Hook up vpu4 op with vpu4 specific implemtation or resue from
earlier generation wherever feasible, like clock calculation in this
case.

Add support for V4L2 streaming operations on the encoder video device.
During stream-on, configure mandatory properties on the respective
planes and notify the firmware to initiate an encode session.

The vpu33 HW is very close to vpu3, and shares most of the
operations, so rename file to vpu3x since we'll handle all vpu3
variants in it.

Build-testing on x86 showed two modules with conflicting "iris.ko"
names after the addition of the qualcomm driver:

   error: the following would cause module name conflict:
     arch/x86/platform/iris/iris.ko
     drivers/media/platform/qcom/iris/iris.ko

Since this a new module, nothing should rely on the name yet, so
rename this one to a more specific "qcom-iris.ko".

During the stream on operation, send HFI_CMD_START on the capture and
output planes to start processing on the respective planes.

During the stream off operation, send HFI_CMD_STOP to the firmware,
which is a synchronous command. After the response is received by the
firmware, the session is closed on the firmware.

Introduce different states for the instance and state transitions.

IRIS_INST_INIT - video instance is opened.
IRIS_INST_INPUT_STREAMING - stream on is completed on output plane.
IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane.
IRIS_INST_STREAMING - stream on is completed on both output and capture
planes.
IRIS_INST_DEINIT - video instance is closed.
IRIS_INST_ERROR - error state.
