ASoC: cs35l56: Accept values greater than 0 as IRQ numbers
IRQ lookup functions such as those in ACPI can return error values when
an IRQ is not defined. The i2c core driver converts the error codes to a
value of 0 and the SPI bus driver passes them unaltered to client device
drivers.
The cs35l56 driver should only accept positive non-zero values as IRQ
numbers.
