[PATCH v6 3/3] ACPI / spi: attach gpio irq from acpi description to spi device

[Christophe Ricard <christophe.ricard@xxxxxxxxx>]

spi->irq was ignoring GpioInt property setting it to -1.
acpi_dev_gpio_irq_get returns and configure the slave irq according to
the acpi slave node description.
It is now inline with devicetree behavior.
