The u8 field contained the actual tx power and a tolerance field, which no physical radio every used. Adjust sysfs entries to keep compatibility with userspace, give tolerances of +-1dB statically there. This patch only adds support for this in the at86rf230 driver and the RF212 chip. Configuration calculation for RF212 is also somewhat basic, but does the job - the RF212 datasheet gives a large table with suggested values for combinations of TX power and page/channel, if this does not work well, we might have to copy the whole table.
