PWR clock is required for various operations.
It is enabled by default in clock control driver,
but disabled at clock init.
It appears soc init is run after clock control driver init
and hence PWR is disabled to to this piece of code at
soc init level.
Don't disable PWR here.
(But keep PWR clock enable in case of ...).
A whole clock clean up will be required later on,
but waiting for that to happen, this is the safest we can do.

CORTEX_M_SYSTICK should be disabled if LPTIM is selected.
Current implementation is not efficient to do so.

In some stm32 series systick was disabled in order to
allow alternate use of lptim timer as kernel low power ticker.
Doing this, dts based definition of CORTEX_M_SYSTICK Kconfig symbol
is disabled and CORTEX_M_SYSTICK was redefined with 'default y'
in stm32 soc files which makes things more complex to handle to
alternate with LPTIM activation.

The STM32F105xx is effectively an STM32F107xx without Ethernet. As such,
it's possible to include the STM32F105's device tree from STM32F107, and
add in any additional nodes (currently just DMA2, though according to
the datasheet, this may be supported by the STM32F105xx and other parts
too).
