gpio: aspeed: Create llops to handle hardware access

Browse Source

Add low-level operations (llops) to abstract the register access for GPIO
registers and the coprocessor request/release. With this abstraction
layer, the driver can separate the hardware and software logic, making it
easier to extend the driver to support different hardware register
layouts.
