Mats Engstrom c1d49fe58b Add iteration over list of frequencies for best solution 
This patch adds support for icepll to try multiple input frequencies to
find the best crystal for the desired output frequency.

The values tested comes either from a specified file using-B, or from a
default set of frequencies from Mousers "normally stocked" crystal
oscillators.

C-Elegans 7201da8cfd Update PLL DIVF range to be [0,127] 
As discussed in issue #83, the range of the DIVF parameter in the
iCE40 PLL Usage Guide is incorrectly listed as being 0-63, when it
should actually be 0-127 when used in the SIMPLE feedback mode. This
however does apply in other feedback modes, where the DIVF range should
still be restricted to 0-63
