flashchips: Add Spansion (today Infineon) S25FL128L and S25FL256L
These chips seem to be rather regular, supporting 2.7V..3.6V, the
common erase block sizes 4KiB, 32KiB, 64KiB and the usual block-
protection bits.
Status/configuration register naming differs from other vendors,
though. These chips have 2 status registers plus 3 configuration
registers. Configuration registers 1 & 2 match status registers
2 & 3 of what we are used from other vendors. Read opcodes match
too, however writes are always done through the WRSR instruction
which can write up to 4 bytes (SR1, CR1, CR2, CR3).
S25FL256L supports native 4BA commands and entering a 4BA mode.
However, it uses an unusual opcode (0x53) for the 32KiB 4BA block
erase.
