mimxrt/machine_uart: Add the UART class to the machine module.
The implementation uses the LPUARTx devices. Up to 8 UARTs can be used, given that the pins are accessible. E.g. 8 on Teensy 4.1, 5 on MIMXRT1020_EVK. For Tennsy 4.0 and 4.1 the UART numbers are as printed on the pinout 1..N. The MIMXRT10xx-EVK boards have only one UART named, which gets the number 1. All other UART are assigned to different Pins: MIMXRT1010-EVK: D0/D1 UART 1 D6/D7 UART 2 A0/D4 UART 3 MIMXRT1020-EVK: D0/D1 UART 1 D6/D9 UART 2 D10/D12 UART 3 D14/D15 UART 4 A0/A1 UART 5 MIMXRT1050-EVK, MIMXRT1060-EVK, MIMXRT1064-EVK: D0/D1 UART 1 D7/D6 UART 2 D8/D9 UART 3 A1/A0 UART 4
