serial: fsl_lpuart: Remove the alias node dependence
Numbering the ttyLPn space should not depend on the generic name
"serial<n>".
If don't add the alias node like:"serial0 = &lpuart0;", then lpuart
will probe failed:
[ 0.773410] fsl-lpuart 2950000.serial: failed to get alias id, errno -19
So remove the alias node dependence, and add the support for allocate the
line port automatically.
