Its good if this is called irqcrossbar_init() to avoid confusion
with the dma crossbar which also exists in dra7 devices.

 Ya makes sense. Will change this.

Also why not call it without explicit soc check? there is already
parse for of_find_matching_node(NULL, crossbar_match); to see if we
have a match in the crossbar_init. OR call it from dra7 init without
SoC check dependency?

Rationale - with more TI SoCs trending towards crossbar, we dont need
to keep adding to the soc_is checks, further, we intend to remove
soc_is checks in it's entirety..
