[PATCH v1 4/6] gpiolib: acpi: Consolidate debug output in acpi_gpio_update_gpiod_flags()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

We have the duplicated debug strings printed whenever
acpi_gpio_update_gpiod_flags() fails. Instead of doing this by callers,
move the debug output inside function.

In one case convert almost useless pr_debug() to dev_dbg() where
actual consumer of GPIO resource is disclosed.
