This patch is similar to that for bfin-uart hardware flow control.
Sport emulated serial device may be probed earlier before GPIOLIB is initialized.
Requesting and configuring CTS GPIO PIN fails in that early stage.

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).
So now this flag is a NOOP and can be removed.

Using C line continuation inside format strings is error prone.
Clean up the unintended whitespace introduced by misuse of \.
Neaten correctly used line continations as well for consistency.
drivers/scsi/arcmsr/arcmsr_hba.c has these errors as well,
but arcmsr needs a lot more work and the driver should likely be
moved to staging instead.

sport->port.irq is unsigned, check for <0 doesn't make sense.
Explicitly cast it to int to check for error.

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
