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".

media: iris: implement vb2 streaming ops

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.

media: iris: introduce host firmware interface with necessary hooks

The Host firmware interface (HFI) is a well defined set of interfaces
for the communication between the host driver and the firmware. The
commands and responses are exchanged in form of packets. One or multiple
packets are grouped under the packet header. Each packet has a packet
type which describes the specific HFI and the payload, which holds the
corresponding value for that HFI.

media: iris: introduce iris core state management with shared queues

Introduce a core state management for iris driver with the necessary
queues needed for the host firmware communication.

There are 3 types of queues:
Command queue - driver to write any command to firmware.
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.
IRIS_CORE_ERROR - error state.
