The dvb-pll sleep function could only send a 2-byte sequence to the PLL. This isn't enough in some cases, for example fmd1216me will need to send a 4-byte command to set both BB and AB to the correct values. Instead of using a fake band with a frequency of 0 to store the sleep data (which has room for only two bytes), the new sleep function works like the init function. A new pointer is added to the pll description, and when non-NULL points to a buffer with the length and data to send.
