dvb-pll: Add support for Alps TDEE4 DVB-C NIM
From: Trent Piepho <xyzzy@speakeasy.org>
No datasheet, data take from code in flexcop driver. That code rounded
down the divisor rather than rounding to nearest, which was probably not
intentional and the dvb-pll code will round to nearest.
Priority: normal
