flashchips: Add SST26VF080A
Simple 8Mbit SPI flash, with one caveat though: SFDP reports 0xd8 as
both 32KiB and 64KiB eraser. The datasheet[1] lists this too in the
SFDP table, however otherwise consistently states that erase blocks
are uniform, and lists 0x52 as the 32KiB eraser. For now, we'll try
the latter.
