media: staging/ipu7: cleanup the MMU correctly in IPU7 driver release
IPU7 ISYS and PSYS auxiliary devices are released after
ipu7_bus_del_devices(), so driver can not reference the MMU devices
from ISYS and PSYS auxiliary devices, so move the MMUs cleanup before
releasing the auxiliary devices.

media: staging/ipu7: add IPU7 input system device driver
The main input system driver mainly cover the basic hardware setup, v4l2
devices registration, firmware stream interfaces and interrupt handling.
Input system CSI2 receiver is exposed as a v4l2 sub-device. Each CSI2
sub-device represent one single CSI2 hardware port which be linked with
external sub-device such camera sensor by linked with ISYS CSI2's sink
pad. The CSI2 source pad is linked to the sink pad of video capture device.
Register V4L2 video device and setup the VB2 queues to support video
capture. Video streaming callback will trigger the input system driver to
construct a input system stream configuration for firmware based on data
type and stream ID and then queue buffers to firmware to do capture.
IPU7 CSI-2 D-PHY hardware is a Synopsys DWC MIPI CSI2 Rx IP, the driver
program the DPHY to receive MIPI data from camera sensors.

media: staging/ipu7: add firmware parse, syscom interface and boot
IPU7 irmware is generated and released as signed Code Partition
Directory (CPD) format file which is aligned with the SPI flash code
partition definition. The driver parses the CPD based on the layout.
Syscom is an inter-process(or) communication mechanism between an IPU and
host. Syscom uses message queues for message exchange between IPU and
host. Each message queue has its consumer and producer, host queue
messages to firmware as the producer and then firmware to dequeue the
messages as consumer and vice versa. IPU and host use shared registers or
memory to reside the read and write indices which are updated by consumer
and producer.
IPU7 firmware defined its boot sequence, driver setup the boot
configuration and program the boot parameters to start and run
the firmware.

media: staging/ipu7: add IPU7 DMA APIs and MMU mapping
The Intel IPU7 has internal microprocessor which runs the firmware
The microprocessor accesses system DRAM by its internal 32-bit virtual
address space. Driver should setup the MMU table and expose the DMA
APIs for memory buffer mapping.
This patch adds the IPU MMU and a DMA mapping implementation to setup
the internal MMU hardware.
