Support for m88rs2000 chip used in lmedm04 driver. Note there are still lock problems. Slow channel change due to the large block of registers sent in set_frontend. Version 2 differences. Front end is completely shut down when in sleep mode. This allow user to regain control of device. Kaffeine scan problem solved by removing register calls from get_frontend. Kaffeine seems to call get_frontend when updating signal data. This can happen in the middle of a tune stalling the driver. Change calculations to those in the DS3000 driver.
