spi: microchip-core: fix potentially incorrect return from probe
If platform_get_irqi() returns 0, the error case will be triggered but
probe() will return 0 rather than an error. Ape the other drivers using
this pattern and return -ENXIO.

spi: fix platform_no_drv_owner.cocci warning
Remove .owner field if calls are used which set it automatically.
Eliminate the following coccicheck warning:
./drivers/spi/spi-microchip-core.c:624:3-8: No need to set .owner here.
The core will do it.
