[PATCH v2 3/4] ARM: shmobile: marzen-reference: Initialise irqpin

[Simon Horman]

Empirically it appears to be necessary to call r8a7779_init_irq_extpin(1)
in order to initialise irqpin for use with IRQ1. This is already done in
the marzen board code. This adds the call to the marzen-reference board
code.

The motivation for this is to allow use of SMSC LAN, which uses IRQ1, with
marzen-reference.
