staging: axis-fifo: Clean up register and mask definitions

Improve readability and consistency of hardware register definitions:
- Remove unnecessary leading zeros from register offset values
- Use BIT() macro for single-bit interrupt mask definitions
- Align values and comments for better readability

No functional change.
