FDT gpio drivers have an extra .xlate operation, so they need to embed
the `struct fdt_driver` inside the subsystem-specific type. The gpio
subsystem always initializes the driver for a specific DT node.

Convert static array to sbi_list.
This removes size limitation, makes add/remove more efficient and
saves space.

We add generic GPIO configuration library which is independent of
hardware description format (FDT or ACPI). The OpenSBI platform
support or GPIO drivers can register GPIO chip instances which
can be discovered and used by different GPIO clients. Each GPIO
chip instance has a unique ID which can be used by GPIO clients
to lookup GPIO chip instance.
