transceiver: simplify transmit power control
UHD will internally accept floats with a range of +/-1.0, which corresponds to a 16-bit signed integer range of apporximately +/- 32000. Set the default amplitude to .3, which is a safe value agaist saturation elsewhere in the transmit chain. The non-UHD maximum amplitude is unchanged at 13500. Remove digital gain control because it's unnecessary and causes extra load on enbedded systems.
