spi/mpc8xxx: don't check platform_get_irq's return value against zero
platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Make irq a signed variable and compare irq <= 0. Note
that a return value of zero is still handled as error even though this
could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.
