OMAP2/3: Pass irqflags to 8250 driver

Pass irqflags to 8250 driver with platform_data. At least Zoom2 has IRQF_TRIGGER_RISING requirement for the 8250 GPIO irq. This patch is dependent on 8250 driver changes getting accepted upstream: http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commit;h=7053133124d5cdf207c1168c7a0c582a18e12ea7 Signed-off-by: Vikram Pandita <vikram.pandita@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
