gpiolib: acpi: Deduplicate some code in __acpi_find_gpio()

__acpi_find_gpio() calls two functions depending on the supplied con_id
and possibility to fallback to _CRS lookup. Those functions have the same
pieces of code that can be done only in one place. Do it so.

This gives an impressive shrink of the generated code for x86_64:

add/remove: 0/2 grow/shrink: 0/4 up/down: 0/-1204 (-1204)
Function                                     old     new   delta
acpi_find_gpio.__UNIQUE_ID_ddebug478          56       -     -56
acpi_dev_gpio_irq_wake_get_by.__UNIQUE_ID_ddebug480      56       -     -56
