[PATCH 2/5 v2] ASoC: mt8173: Fix platform_get_irq's error checking

[Arvind Yadav]

The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.

chnages in v2 :
              irq_id was unsigned. so changed it to signed.
