Calibration process can be simplified if LF clock is always on.
Kconfig was depending on RTC being used as system clock because
that indicates LF clock being always on. Same can be done for
case when GRTC is used as system clock.

Remove the inline attribute from stm32 clock drivers functions
especially for functions that are only referenced in the clock API
operation structure and therefore cannot be inline. As a generic
comment, today compiler are smart enough to optimize embedded software
without needing inline function attributes in the source files.
This change hopes that next stm32 clock driver will no more replicate
this bad habit when using existing source files as implementation
examples.
No functional change.

IN_RANGE() macro from zephyr/sys/util.h returns a boolean value
so it should be treated as such and not compared to a decimal value.
Fix stm32 clock drivers accordingly and simplify places where the
value is compared to true.

Correct typo in STM32H7 HSI clock calibration directives introduced
in commit 6b167f2596 ("drivers: clock_control: add calibration for
h7 pllx_hsi") that currently has no functionnal impact but is worth
to be fixed for consistency.

Remove function exported stm32_system_clock_update() defined in
STM32H7RS series clock driver but that is not used and not even declared.
There already exists a CMSIS SystemCoreClockUpdate() function in
STM32 HAL drivers for the exact same purpose one may use if needed.

Currently, siwx917 have three instances of uart: ulpuart, uart1 and
uart2. However:
- The other drivers on siwx91x (i2c, dma, i2s, etc...) rather use
'ulp', '0' and '1'.
- The reference manual also uses 'ulp', '0' and '1'.
The source of the confusion probably come from the clock driver in
WiseConnect which use clocks USART1 and USART2. However, this probably
not expected.
So, this patch renames uart1 and uart2 in uart0 and uart1. This change
also impacts the names of pins and the names of the clocks.

This driver is mostly the initial seed for further implementation of a
real clock driver.
It doesn't allow the user to choose the clock source for the various
peripherals. The driver hardcodes some sane values.
Note that for now, the driver snps,designware-i2c does not support
"clocks" attribute. So this patch hardcode the clock configuration in
the init of the clock driver.
