gpio: loongson-64bit: Extend GPIO irq support

[ Upstream commit 27cb8f702eb789f97f7a8bd5a91d76c65a937b2f ]

Add the interrupt enable register offset (inten_offset) so that GPIO
interrupts can be enabled normally on more models.

According to the latest interface specifications, the definition of GPIO
interrupts in ACPI is similar to that in FDT. The GPIO interrupts are
listed one by one according to the GPIO number, and the corresponding
interrupt number can be obtained directly through the GPIO number
specified by the consumer.
