[i2c, dv] Updates for both i2c_agent and i2c_sanity
1) i2c_agent
- Add knob to control target address mode (7-bit: current support, 10-bit: RFU)
- Update agent to support re-programming registers from test
- Remove unused macros
2) i2c_sanity
- Support re-programming timing regs during tranceiving tran in i2c_sanity
- Add knob to control target address mode
