devices: MIMX8UD7: add definition for LPUART_RX_TX_IRQS

Add definition for the `LPUART_RX_TX_IRQS` macro. This is
required by the `fsl_lpuart` driver to work. The definition
of the macro is just an array of `NotAvail_IRQn` because the
HIFI4 DSP doesn't receive interrupts from any of the LPUART
instances.
