mtd: rawnand: gpmi: add debugfs entry for BCH geometry

Browse source

Export the BCH geometry parameters via debugfs to aid debugging and
provide the necessary information for legacy kobs-ng tool. The debugfs
directory "gpmi-nand" is created under the root debugfs tree, exposing:

bch_geometry  - blob containing the struct bch_geometry fields
raw_mode      - flag indicating raw mode status

The implementation is guarded with #ifdef CONFIG_DEBUG_FS to avoid
build failures when debugfs is disabled.
