This patch distributes the Local Oscillator calibration bursts over time, so that calibration only happens when it's actually needed. Currently we periodically perform a recalibration of the whole table. The table is huge and this takes lots of time. Additionally only small bits of the table are actually needed at a given time. So instead of maintaining a huge table with all possible calibration values, we create dynamic calibration settings that a) We only calibrate when they are actually needed. b) Are cached for some time until they expire. So a recalibration might happen if we need a calibration setting that's not cached, or if the active calibration setting expires. Currently the expire timeout is set to 30 seconds. We may raise that in future. This patch reduces overall memory consumption by nuking the huge static calibration tables. This patch has been tested on several 4306, 4311 and 4318 flavours.
