Log:
More range for HT_CHAIN_UNITID_BASE and HT_CHAIN_END_UNITID_BASE.
For example: in C51/MCP55 or C51/MCP51
Will allow
1. C51 at 0x10 to 0x14, and MCP at 0 to 4
2. C51 at 1 to 4, and MCP at 7 to 0x0a
The reason is c51/mcp51/mcp55 reported unitid is 0x0f (far beyond it
needed), and will prevent us from putting them on bus 0.
Typical values for c51/mcp55 or c51/mcp51:
HT_CHAIN_UNITID_BASE = 0x10 # for C51
HT_CHAIN_END_UNITID_BASE = 0 # for mcp
If only have mcp with c51,
HT_CHAIN_UNITID_BASE = 0 # for MCP
#HT_CHAIN_END_UNITID_BASE = 0 # default value 0x20
