During system bootimg, drm probe will fail since failed to bind all
devices, currently the iommu init is done before bind all devices,
the iommu needs to clean up.
This patch moves the iommu init after bind all devices to reduce the
iommu clean up.

The LSM6DSR is a system-in-package featuring a 3D digital accelerometer
and a 3D digital gyroscope with an extended full-scale range for the
gyroscope, up to 4000 dps, and high stability over temperature and time.
The LSM6DSR features the following on-chip functions:
* 9 kbytes data buffering, data can be compressed two or three times
* Event-detection interrupts (fully configurable):
- Free-fall
- Wakeup
- 6D orientation
- Click and double-click sensing
- Activity/inactivity recognition
- Stationary/Motion detection
* Specific IP blocks with negligible power consumption and
high-performance
- Pedometer functions: step detector and step counters
- Tilt
- Significant Motion Detection
- Finite State Machine (FSM) for accelerometer, gyroscope, and external
sensors
* Sensor hub
- Up to 6 total sensors: 2 internal (accelerometer and gyroscope) and 4
external sensors
* S4S data rate synchronization with external trigger for reduced sensor
access and enhanced fusion
Current driver offers support for accelerometer and gyroscope.

Add FIFO event type:
* IIO_EV_TYPE_FIFO_FLUSH
This change also adds FIFO event directions:
* IIO_EV_DIR_FIFO_EMPTY (indicates the FIFO is empty)
* IIO_EV_DIR_FIFO_DATA (indicates the FIFO is not empty)
A FIFO flush event is triggered after the HW FIFO is flushed,
and indicates that whether the HW FIFO is empty or not.

There are AVDD and GPIO0/CE in the pinout of STMicro VL6180:
- AVDD (Digital/analog power supply 2.6 to 3.0 V),
- GPIO0/CE (Power-up default is chip enable (CE)).
These two pins are gpio connected in some reference design boards and
control the power in the Power-up timing constraints. This patch
emulates this situation.

For various reasons based on the allocator behaviour and typical
use-cases at the time, when the max32_alloc_size optimisation was
introduced it seemed reasonable to couple the reset of the tracked
size to the update of cached32_node upon freeing a relevant IOVA.
However, since subsequent optimisations focused on helping genuine
32-bit devices make best use of even more limited address spaces, it
is now a lot more likely for cached32_node to be anywhere in a "full"
32-bit address space, and as such more likely for space to become
available from IOVAs below that node being freed.
At this point, the short-cut in __cached_rbnode_delete_update() really
doesn't hold up any more, and we need to fix the logic to reliably
provide the expected behaviour. We still want cached32_node to only move
upwards, but we should reset the allocation size if *any* 32-bit space
has become available.
