irq: Kill pointless irqd_to_hw export
It makes no sense to export this trivial function. Make it a static inline instead. This patch also drops virq_to_hw from arch/c6x since it is unused by that architecture. v2: Move irq_hw_number_t into types.h to fix ARM build failure Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Thomas Gleixner <tglx@linutronix.de> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>
