irqchip: irqc: Remove platform data support 



As of commit 914d7d14 ("ARM: shmobile: r8a73a4: Remove legacy
code"), the Renesas R-Mobile/R-Car interrupt controller is used with DT
only, and interrupt numbers are thus always assigned automatically.

Drop the platform data declaration and all related support code.
