robert-hh 689476c576 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
