Public bug reported:

SRU Justification

[Impact]

The latest PR to fix a certification issue has introduced a build failure. 
Specifically:  
net: mellanox: mlxbf_gige: Replace non-standard interrupt handling

A build of the kernel fails with the following error:
drivers/net/ethernet/mellanox/mlxbf_gige/mlxbf_gige_main.c:380:12: error: 
implicit declaration of function 'acpi_dev_gpio_irq_get_by'; did you mean 
'acpi_dev_gpio_irq_get'? [-Werror=implicit-function-declaration]

[Fix]
Cherry-picking:
809390219fb9c gpiolib: acpi: Allow to find GpioInt() resource by name and index

The above commit reworks GpioInt() to allow finding the resource via
name and index while preserving previous functionality.

[Test Case]
Beyond ensuring build still works, no testing of drivers using the reworked 
acpi_dev_gpio_irq_get function will be done, but it should still work as 
previously designed when NULL is passed for name.

[Where problems could occur]
Chance of regression should be very low with this change.
