bhyve.8: Improve emulation description of the -s flag
- Set width of the list to the longest key word for readability. - Separate descriptions of amd_hostbridge and hostbridge emulations. Also, wordsmith their descriptions for consistency with other entries. - Use Cm instead of Li for command modifiers. - Do not stylize AMD with Li, there's no need to do it. - Mention COM3 and COM4 in the definition of lpc. - Fix a typo in the definition of ahci-hd ("hard drive" instead of "hard-drive"). MFC after: 2 weeks
