spi: mediatek: Enable irq before the spi registration
If the irq is enabled after the spi si registered, there can be a race
with the initialization of the devices on the spi bus.
Eg:
mtk-spi 1100a000.spi: spi-mem transfer timeout
spi-nor: probe of spi0.0 failed with error -110
Unable to handle kernel NULL pointer dereference at virtual address
0000000000000010
...
Call trace:
mtk_spi_can_dma+0x0/0x2c
Fixes: c6f7874687f7 ("spi: mediatek: Enable irq when pdata is ready")
