Trammell Hudson 9abf7d8468 icenvcm: Program the iCE40 NVCM 
icenvcm will write a bitstream into an iCE40 device with
one-time-programmable non-volatile configuration memory (NVCM)
and optionally set the security lock bits to prevent read out.

This is a dangerous operation and can result in bricked devices.
Since it is OTP, you must be sure that your design is good enough to
permanently burn into the chip.  It is still possible to use the iceprog
-S to reconfigure the SRAM, although the FPGA will no longer boot from
an attached SPI flash.

Note that the NVCM requires a 2.5V power supply, which the Lattice
devboard (and many other third party boards) do not include.
A schematic is included for a ZIF programming jig to burn the chips
before they are soldered to their final boards.

Sylvain Munaut ce1d811d21 icebox: Add support for the bit 1 of SHIFTREG_DIV_MODE on UP5k 
This allows selection of the div-by-5 mode of the PLL.
This bit can't be fuzzed because it's not supported by the lattice
tools at all ...

This only works for sure on the UP5k.

I tested HX8k and it didn't support it, so I'm only adding this on
the known working FPGA.

Ed Maste e52149944e icetime: avoid string + int Clang warning 
Clang warns that "adding 'int' to a string does not append to the string".
Although a false positive it's trivially avoided by using the array index
equivalent &PREFIX[1].
