ASoC: renesas: fsi: Propagate platform_get_irq() errors

Browse Source 
platform_get_irq() returns a positive IRQ number on success and a
negative error code on failure. It no longer returns zero. The driver
currently stores the return value in an unsigned int and returns -ENODEV
for all failures, which loses useful errors such as -EPROBE_DEFER.

Store the IRQ in an int and return the error from platform_get_irq()
directly.
