Fixed STM32L4_NUSART for STM32L433XX. ( #9 )
...
STM32L4_NUSART was set to 4. The spec at
https://www.st.com/resource/en/datasheet/stm32l433cc.pdf states the
following on page 1:
- 4x USARTs (ISO 7816, LIN, IrDA, modem)
- 1x LPUART (Stop 2 wake-up)
However it on page 49, it states:
The STM32L433xx devices have three embedded universal synchronous
receiver transmitters (USART1, USART2 and USART3).
The latter is correct.
This patch sets STM32L4_NUSART to 3.

In the current implementation we only use very high priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but that means there are loads of lower priority ones that are effectively unused. I have *not* changed the semantics of these levels but have 'shifted' them to be based around the midpoint of the available interrupts (0x80) rather than at the top end....that allows for interrupts to be defined above (or, indeed, below) them as needed by the application. This should have no functional effect on existing code but adds in a clean capability to define higher priority interrupts.

arch/arm/src/stm32l4: Avoid using redundant CONFIG_STM32L4_STM32L4X2. This is almost always same as CONFIG_STM32L4_STM32L4X3. Avoid duplication to reduce macro clutter. This patch limits CONFIG_STM32L4_STM32L4X2 usage to dependency tracking and pinmap. Also enable ADC for CONFIG_STM32L4_STM32L4X5 (untested, but same RM).

STM32L4: changes needed for STM32L452 and Nucleo-L452RE board
...
GPIO and UART seem similar across STMicro product matrix,
so renamed files accordingly. RCC is cloned just in case,
while conflicting differences there seem to be very minor.
