include: stm32: clock_control: Ease usage of STM32_DT_CLOCKS macro

STM32_DT_CLOCKS was designed to take a device tree node label name as
argument: STM32_DT_CLOCKS(uart1)
Change its implementation to take a node identifier instead:
STM32_DT_CLOCKS(DT_NODELABEL(uart1)).

This make its usage more flexible since the argument can now be extracted
from other DT macros such as DT_PARENT. Then, the following can be done:
STM32_DT_CLOCKS(DT_PARENT(child_node_label)).

Since it is now possible implement STM32_DT_INST_CLOCKS using
STM32_DT_CLOCKS.

Finally, update existing STM32_DT_CLOCKS users and convert
STM32_INST_CLOCK_INFO users to STM32_CLOCK_INFO.
