* UART9 was supported as LPUART on some H7s. * Newer 100-pin H7 CPUs support UART9 and USART10. * 100+ pin devices support higher numbered UARTS than UART10. Use USE_LPUART instead of hacking into UART9 for clarity. * LPUARTS are different from other types of UARTS. * They need different ID ranges. * They have and different capabilities. * Renumber LPUART1 to 40. 0-19 reserved for UART1-20 40-49 onwards for LPUART instances. It makes sense to treat them as a different class of UART. Just like we do for softserial, vcp, etc.
