Normally we don't do this, but enough changes have accumulated that
we're doing a tree-wide one-off update of the name & style.

Use CONFIG_<driver>_INT_ENABLE to not include interrupt() and
irq_handler() when hardware interrupt are not used.
Disable call to motion_sense_fifo() with IS_ENABLED(CONFIG_ACCEL_FIFO).
Other use of CONFIG_ACCEL_FIFO are removed: only when a hardware
interrupt is configured we enable the sensor FIFO.
Otherwise we directly read into the sensor data registers.

Add a loop in irq_handler to match datasheet documentation:
"""
1. Read the FIFO_STATUS1 and FIFO_STATUS2 registers to check how many
words are stored in the FIFO. This information is contained in the
DIFF_FIFO_[9:0] bits.
2. For each word in FIFO, read the FIFO word (tag and output data) and
interpret it on the basis of the FIFO
tag.
3. Go to step 1.
"""
We need to read the FIFO length at the end of the IRQ handler to be
sure a new item has not been put while the FIFO was being read.
Otherwise, we will not get interrupt and will stop processing FIFO when
the FIFO status register still shows the FIFO as not empty.
However, using linux kernel st_lsm6dsx_read_tagged_fifo() as model,
read only one word at a time:
When reading 2 7bytes word at time, the FIFO would still claim one entry
remains: The 3rd entry would be a copy of the accelerometer data, but
with a corrupted z axis.That why we fail the data test, the gravity
vector is not measured at 9.81m/s^2.
There was a bug in the interrupt handler that would read the FIFO twice,
which was presenting the data: both gyro and accel at the same ODR:
[7623.475256 Base Accel FIFO status: 8002]
[7623.476548 Base Gyro sending vector num: 2
raw: 0x00000007 - 0xFFFFFFF6 - 0xFFFFFFF9]
[7623.477526 Base Accel sending vector num: 1
raw: 0xFFFFFFCC - 0xFFFFE275 - 0xFFFFE818]
[7623.479271 Base Accel FIFO status: 8001]
[7623.480333 Base Accel sending vector num: 1
raw: 0xFFFFFFCC - 0xFFFFE275 - 0x00000C18]
[7623.481699 Base Accel FIFO status: 0000]
We must only run the irq_hanlder for the main/accelerometer sensor.
Restructure irq_hanlder to match other driver, like accelgyro_bm160.c.

Rename LSM6DSO_FIFO_ODR_TO_REG into LSM6DSO_FIFO_ODR_MASK as the macro
return the mask to use to set the FIFO ODR.
Remove CONFIG_EC_MAX_SENSOR_FREQ_MILLIHZ in code, as already used in
LSM6DSO_ODR_MAX_VAL.
Simplify LSM6DSO_ST_DATA by using . instead of ->.

The extentions were added to make the compiler perform most
of the verification that the conversion was being done correctly
to remove 8bit addressing as the standard I2C/SPI address type.
Now that the compiler has verified the code, the extra
extentions are being removed

Opt for 7bit slave addresses in EC code. If 8bit is
expected by a driver, make it local and show this in
the naming.
Use __7b, __7bf and __8b as name extensions for i2c/spi
addresses used in the EC codebase. __7b indicates a
7bit address by itself. __7bf indicates a 7bit address
with optional flags attached. __8b indicates a 8bit
address by itself.
Allow space for 10bit addresses, even though this is
not currently being used by any of our attached
devices.
These extensions are for verification purposes only and
will be removed in the last pass of this ticket. I want
to make sure the variable names reflect the type to help
eliminate future 7/8/7-flags confusion.

- ODR and FS runtime configuration
- FIFO water mark interrupt
- Shared commons function with ST MEMs devices
BUG=none
BRANCH=master
TEST=Tested on discovery target BOARD with
LSM6DSO connected to EC i2c master bus and motion
sense task running.
Commands used to test LSM6DSO device are:
- accelinit
- accelrange
- accelinfo
All basic features tested, including:
1) ODR change:
- accelrate 0 [13000:208000]
- accelrate 1 [13000:208000]
2) FS Range change:
- accelrange 0 [2:16]
