gpio: graniterapids: Fix vGPIO driver crash

In the Linux kernel, the following vulnerability has been resolved:

gpio: graniterapids: Fix vGPIO driver crash

Move setting irq_chip.name from probe() function to the initialization
of "irq_chip" struct in order to fix vGPIO driver crash during bootup.

Crash was caused by unauthorized modification of irq_chip.name field
where irq_chip struct was initialized as const.

This behavior is a consequence of suboptimal implementation of
gpio_irq_chip_set_chip(), which should be changed to avoid
casting away const qualifier.
