Subject: [PATCH v3 0/2] gpio: mlxbf2: Introduce proper interrupt handling

This is a follow up on a discussion regarding
proper handling of GPIO interrupts within the
gpio-mlxbf2.c driver.

Link to discussion:
https://lore.kernel.org/netdev/20210816115953.72533-7-andriy.shevchenko@linux.intel.com/T/

Patch 1 adds support to a GPIO IRQ handler in gpio-mlxbf2.c.
Patch 2 is a follow up removal of custom GPIO IRQ handling
from the mlxbf_gige driver and replacing it with a simple
IRQ request. The ACPI table for the mlxbf_gige driver is
responsible for instantiating the PHY GPIO interrupt via
GpioInt.

Andy Shevchenko, could you please review this patch series.

v3 vs. v2 patch:
- Add IRQ_TYPE_LEVEL* back to mlxbf2_gpio_irq_set_type.
  YU_GPIO_CAUSE_FALL_EN and YU_GPIO_CAUSE_RISE_EN
  are configured in Both level and edge interrupts cases.
