[PATCH -next 1/2] spi: Remove unnecessary print function dev_err()

[Yang Li]

The function platform_get_irq() never returns 0, and the print function
dev_err() is redundant because platform_get_irq() already prints an error.

Eliminate the follow coccicheck warning:
./drivers/spi/spi-microchip-core.c:543:2-9: line 543 is redundant
because platform_get_irq() already prints an error
