Refactor amdxdna GEM buffer object (BO) handling to simplify address management and unify BO type semantics. Introduce helper APIs to retrieve commonly used BO addresses: - User virtual address (UVA) - Kernel virtual address (KVA) - Device address (IOVA/PA) These helpers centralize address lookup logic and avoid duplicating BO-specific handling across submission and execution paths. This also improves readability and reduces the risk of inconsistent address handling in future changes. As part of the refactor: - Rename SHMEM BO type to SHARE to better reflect its usage. - Merge CMD BO handling into SHARE, removing special-case logic for command buffers. - Consolidate BO type handling paths to reduce code duplication and simplify maintenance. No functional change is intended. The refactor prepares the driver for future enhancements by providing a cleaner abstraction for BO address management.
