Sylvain Munaut 98d8bee04f iceprog: Use open-drain output to drive SS and Reset line

Sylvain Munaut c5a8beffec iceprog: Improve reset to disable both CRM and QPI 
It's hard to cover 100% of cases, but this seems to improve
probability that a reset works, at least for me on the icebreaker.

Some other flash have a different QPI disable command though :/

Sylvain Munaut 502d847b41 iceprog: Add option that set QE=1 bit in SR2 
This is useful when testing litex SoC that rely on that bit being set

The setting is non-volatile so it only needs to be done once in case
you happen to have used a flash chip that's not by default QE=1

(This has been designed for winbond flash. Others might use
 different bit ...)

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].
