media: iris: rename module file

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".

client, before the VIDIOC_DECODER_CMD() was issued and mark the last
buffer with the V4L2_BUF_FLAG_LAST flag. The decoder is stopped, after
processing the last buffer.

Resume the decoder when one of these operations are issued by the client:
- V4L2_DEC_CMD_START
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE queue
- pair of VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the OUTPUT queue

Add the handling to resume decoding when client issues
V4L2_DEC_CMD_START to resume decoding after a source change is detected.

firmware, the session is closed on the firmware.

IRIS_INST_INIT - video instance is opened.
IRIS_INST_INPUT_STREAMING - stream on is completed on output 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.

Message queue - firmware to send any response to the driver.
Debug queue - for the firmware to write debug messages.
Initialize and configure the shared queues during probe.

Different states for core:
IRIS_CORE_DEINIT - default state.
IRIS_CORE_INIT - core state with core initialized. FW loaded and HW
brought out of reset, shared queues established
between host driver and firmware.
