irqchip/renesas-intc-irqpin: Remove obsolete platform data support

Browse source 
Since commit 4baadb9e05 ("ARM: shmobile: r8a7778: remove obsolete
setup code"), all Renesas SoCs with a renesas-intc-irqpin module are
only supported in generic DT-only ARM multi-platform builds.  The driver
doesn't need to use platform data anymore, hence remove platform data
configuration.
