The IRQCHIP_DECLARE macro migrated to 'include/linux/irqchip.h'.

See commit 91e20b50
("irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h").

This patch removes the inclusions of private header 'drivers/irqchip/irqchip.h'
and if necessary replaces them with inclusions of 'include/linux/irqchip.h'.
