ARM: clps711x: Cleanup IRQ handling
This patch contains two changes: - Removed unused definitions from mach/irqs.h - Do not mask interrupts in ack procedure, because we have separate intX_mask procedure for do it and actually these 2 functions are called sequentially Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
