Enable frequency detection and correction by buffering the previous frame to allow FCCH measurement and compensation after frame timing is locked using the SCH. When the SCH is detected and symbol timing matched, measure the FCCH burst from one frame prior and compensate by baseband tuning the DDC on the device. Avoid appying frequency corrections to the RF portion due to possible tuning delays, which is not an issue with DDC tuning. Signed-off-by: Thomas Tsou <tom@tsou.cc>
