serial: fsl_lpuart: don't modify arbitrary data on lpuart32
[ Upstream commit ccf08fd1204bcb5311cc10aea037c71c6e74720a ]
lpuart_rx_dma_startup() is used for both the 8 bit and the 32 bit
version of the LPUART. Modify the UARTCR only for the 8 bit version.
Fixes: f4eef224a09f ("serial: fsl_lpuart: add sysrq support when using dma")
