Default AHB presacler value was set to 0 which is not an allowed
value. Set it to 1 and limit range from 1 to 512.

Some more were added since the cleanup pass in June 2018. See e.g.
commit 2d50da70a1 ("drivers: ipm: Kconfig: Remove redundant 'default n'
properties") for a motivation. It also avoids people wondering whether
or not they need to put in 'default n'.

Add support for Low Speed External 32.768 kHz oscillator (LSE ).
Add support for MSI PLL-Mode offering an automatic calibration feature
in combination with the LSE. This allows the MSI to reach an accurate
+/-0,25% clock perfectly suitable for USB full-speed clock.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.
This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

MSI clock signal can be selected in several ranges.
These ranges should be taken into account for calculating its
frequency and hence global system frequency.
Provide a Kconfig option to set MSI range.

In stm32 clock_control driver, Kconfig symbol CLOCK_STM32_PLL_PREDIV1
in stm32f3 series was set as conditional on the activation of some
specific STM32F3 SoCs that are not supported yet in Zephyr.
Remove this flag.
In order not to loose a rather studious part of code, comment it out
and set a TODO to specify how to re-enable it once it will be
required.

Add MSI as potential SYSCLK direct source for L0 and L4.
It could be needed in some cases when an accurate clock
is required and no external clock is available.

Remove SoCs part dependency of CLOCK_STM32_PLL_PREDIV1 config since
it will only be used on parts having an HSE oscillator, ignored
otherwise.

This commits align CONFIG_ factor names between stm32f4 and stm32l4
series to enable code factorization such as use of Q_DIVISOR.
Though, it does not concatenate kconfig sections as we might use
a bit of time to see what is needed in this regard

This commit enables STM32Cube LL based driver for stm32f4 series.
This generic driver provides a unified API to clock driver for all
stm32 series.
LL API allows driver to be lightweight and to keep genericity across
stm32 family to ease further devlopment and maintenance.

This new clock control driver aims at providing a lightweight
generic driver to the whole stm32 family.
Driver is based on LL Cube API and hence is for now available
only for STM32 supporting this API: stm32f3xx and stm32l4xx.
Other families should be supported soon.
Once globally supported, this unique driver will also help
reducing the impact of stm32 clock control heterogeneity in
other drivers.
