serial: 8250: add IRQ trigger support
There is currently no provision for passing IRQ trigger flags for
serial IRQs with triggering requirements (such as GPIO IRQs)
This patch adds irqflags to plat_serial8250_port that can be passed
from board file to reqest_irq() of 8250 driver
Changes are backward compatible with boards passing UPF_SHARE_IRQ flag
Tested on Zoom2 board that has IRQF_TRIGGER_RISING requirement for 8250 irq
[Moved new flag to end to fix bugs in the original with the old_serial array
