USB: CP2101 Support AN205 baud rates
This patch adds support for the extended range of baud rates supported by CP2102 and CP2103 devices described in SiLabs AN205. An additional function cp2101_quantise_baudrate rounds the baud rate as per AN205 Table 1. A modification to the baud rate calculation removes a rounding error, allowing the full range of baud rates to be used.
