[v2,2/2] ASoC: fsl_ssi: use platform_get_irq instead of irq_of_parse_and_map

Commit Message

Use platform_get_irq as no mapping needs to be done.
By using platform_get_irq, driver can avoid to free IRQ manually
when SSI driver exits.

Fabio sent a version of this before yours so I applied his, I think the
code is the same.
