Fixed STM32L4_NUSART for STM32L433XX. (#9)

Browse Source 
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.
