[ARM] 5108/2: PXA SSP: Don't unconditionally free interrupt
Callers may stop the SSP core requesting the interrupt so it can't be freed unconditionally. Also use NO_IRQ like we should. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
