Transceiver52M: Add SCH detection capability
Use similar approach for detecting normal and RACH bursts, but apply a sample shift after detection in order to gradually zero the measured timing offset. SCH synchronization sequence and setup are added similar to RACH detection with the main difference, aside being the SCH runs full length of the burst. History is also added to accommodate full length burst correlation. Signed-off-by: Thomas Tsou <tom@tsou.cc>
