8a36cdc8ef gpio: loongson: Remove unnecessary .owner 
Remove .owner field if calls are used which set it automatically.

./drivers/gpio/gpio-loongson-64bit.c:225:3-8: No need to set .owner here. The core will do it.

7944d3b7fe gpio: loongson: add gpio driver support 
The Loongson platforms GPIO controller contains 60 GPIO pins in total,
4 of which are dedicated GPIO pins, and the remaining 56 are reused
with other functions. Each GPIO can set input/output and has the
interrupt capability.

This driver added support for Loongson GPIO controller and support to
use DTS or ACPI to descibe GPIO device resources.
