Subject: tty: serial: imx: remove the use of MXC_INTERNAL_IRQS
As the part of the effort to enable SPARE_IRQ for imx platform,
the macro MXC_INTERNAL_IRQS will be removed. The imx serial driver
has a references to it for a decision on flags of request_irq call
based on rtsirq is beyond MXC_INTERNAL_IRQS. However the searching
on imx platform code tells that rtsirq will never be beyond
MXC_INTERNAL_IRQS. That said, the check, consequently the reference
to MXC_INTERNAL_IRQS are not needed, so remove them.
