[PATCH 05/06] sh: Let INTC set IRQF_VALID on ARM platforms V2

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@opensource.se>

Reuse the SuperH INTC code on ARM by using set_irq_flags()
to set IRQF_VALID on ARM platforms. (V2)

Signed-off-by: Magnus Damm <damm@opensource.se>

 Changes since V1:
 - wrap with CONFIG_ARM instead of CONFIG_ARCH_SHMOBILE
 - use set_irq_flags() in create_irq_nr() as well
