Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver

A coccinelle rule is used for this:

Avoid reading LPTIM counter four times instead of three when second
read doesn't give same value. Use common code, avoid volatile for
local vars.

When setting a timeout K_TICKS_FOREVER,the lptimer clock is stopped
(no reset of the lptim).
Then is the lptim possibly re-started when another source asks for.
The lptim clock must then be re-started and continue counting.
This is the case when wakeup from sleep mode, for example.

Some ticks are counted additionally when the autoreload
interrupts were too close together.
This patch improve the counts of the clock cycle.
lptim_fired worked badly in particular because the flag ARRM
was not raised when the interrupt was forced.

If ticks is K_TICKS_FOREVER the register autoreload isn't set.
So, on the next call to the z_clock_set_timeout function
the wait for the flag ARROK will be infinite.

We don't need to reset backup domain to set LSE clock source.
It's dangerous to reset backup domain, it removes:
- RTC configuration
- backup registers
- RCC Backup domain control register

Some kernel tests use `CONFIG_TICKLESS_KERNEL=n` with
`CONFIG_SYS_CLOCK_TICKS_PER_SEC=1` to detect when a test runs longer
than 1 second. These tests break if a tick is announced every time a
timeout occurs. Only announce if the measured duration since the last
tick is at least the duration of a tick.

to LPTIM_TIMEBASE which is the full register value
In case the timeout is FOREVER, then lptimer is stopped

The current value of the counter must not be added to the accumulator.
It will be added when calling z_timer_cycle_get_32.

When the tickless kernel isn't used, we don't want to wait for ARROK.
This wait can be endless.

Use NODELABEL macros rather than DT_INST as this driver is so far
limited to support of LPTIM1 instance.
