irqchip/s3c24xx: Mark init_eint as __maybe_unused

Browse source 
The init_eint array in the s3c24xx irqchip driver is used by
every individual chip variant, but Kconfig allows building
the driver when they are all disabled, and that leads to
a harmless compile-time warning:

drivers/irqchip/irq-s3c24xx.c:608:28: error: 'init_eint' defined but not used [-Werror=unused-variable]

This marks the array as __maybe_unused to avoid the warning.
