Commit 83a119160 fixed SMP by removing call to uart_xmitchars from inside spinlock. This only works for SMP, since uart_xmitchars has a lock only in SMP. In a single core configuration the function can be called in parallel from the interrupt handler and from the imx9_txint. Fix this by filling the uart buffers already before enabling the interrupt, this way it is not possible to get the function called in parallel for the same device.
