Adding GEN5 files for handling GEN LCE specific operations.
These files are inherited from the existing files/APIs
which has some changes specific GEN5 requirements
Also updated the mailmap file.

---
v5:
- Replaced usage of __u8 with uint8_t.
v3:
- Removed use of linux/kernel.h macro to fix ARM compilation.
- Fixed typo in commit body and code comment.
v2:
- Renamed device from GEN 5 to GEN LCE.
- Removed unused code.
- Updated macro names.
