SPI table updates (some new devices and new info)

Browse Source 
read_cmd, qread_cmd, pprog_cmd added as some recent high densities devices
use variants for 4-byte addressing.

Some new flash and FRAM device ids added. FRAMs don't have write pages nor
erase commands or sector sizes. The corresponding entries are marked as
"not used" (i. e. zero). Checks in existing SPI flash drivers added to
handle these cases gracefully.
