serial: cpm_uart: Don't request IRQ too early for console port
The following message is seen during boot and the activation of
console port gets delayed until normal serial ports activation.
[ 0.001346] irq: no irq domain found for pic@930 !
The console port doesn't need irq, perform irq reservation later,
during cpm_uart probe.
While at it, don't use NO_IRQ but 0 which is the value returned
by irq_of_parse_and_map() in case of error. By chance powerpc's
NO_IRQ has value 0 but on some architectures it is -1.
Fixes: 14d893fc6846 ("powerpc/8xx: Convert CPM1 interrupt controller to platform_device")
