[PATCH 02/14] irqchip: crossbar: fix sparse warnings

[Sricharan R <r.sricharan@ti.com>]

From: Nishanth Menon <nm@ti.com>

There is absolutely no need for crossbar driver to expose functions and
variables into global namespace. So make them all static

Fixes sparse warnings:
drivers/irqchip/irq-crossbar.c:129:29: warning: symbol 'routable_irq_domain_ops' was not declared. Should it be static?
drivers/irqchip/irq-crossbar.c:252:5: warning: symbol 'dra_irqs_unused' was not declared. Should it be static?
drivers/irqchip/irq-crossbar.c:253:22: warning: symbol 'cb_dra_data' was not declared. Should it be static?
drivers/irqchip/irq-crossbar.c:261:12: warning: symbol 'irqcrossbar_init' was not declared. Should it be static?
