Matthew Mets 48ab6c3459 Speed up Pico programmer by switching to raw USB protocol 
This update replaces the HID-based USB protocol with a vendor
control transfer variant. The primary goal is speed- HID transfers
are rate-limited to 1000/s, which gives a maximum transfer rate of
64kb/s. Unfortunately a majority of this bandwidth is wasted, and
typical ice40 flash routines could take up to 17 seconds to
complete. With the switch to a new protocol, the time is reduced to
under 4 seconds.

Trammell Hudson 5b5d7bb3ce docs/format.html: document bram/cram read-back commands 
The Lattice tools use these additional commands to read-back the BRAM
and CRAM after programming to validate that it was written correctly.
`iceprog` doesn't use this right now, so this is just for documentation
purposes.

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 ...)

David Williams e368f15a7f Add an option (-p) to force use of SB_PLL40_PAD 
When a clock is applied to a dedicated clock pin, SB_PLL40_CORE is no longer the correct primitive to use.

Also the name of the clock input must be PACKAGEPIN (rather than REFERENCECLK)
