There is a function, spi_get_erasefn_from_opcode, which returns the
erase function for given opcode. Add a function which does the opposite
i.e. returns the opcode for given erase function.

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.

Wire "variable size" feature in dummy programmer via opaque infra.
This patch fixes the broken build with CONFIG_DUMMY=no.
Dummyflasher registers opaque master for the case when it is
initialised with EMULATE_VARIABLE_SIZE. Dummy opaque master emulates
read/write/erase as simple memory operations over
`data->flashchip_contents`.
The feature works via "Opaque flash chip" in flashchips.c which has
one block eraser at the moment. If this changes in future, each block
eraser needs to be updated in `probe_variable_size`.
Fixes: https://ticket.coreboot.org/issues/365
TEST=the following scenarious run successfully
Testing build
$ make clean && make CONFIG_DUMMY=no
$ flashrom -h : dummy is not in the list
$ make clean && make CONFIG_EVERYTHING=yes
$ flashrom -h : dummy is in the list
Testing "variable size" feature
$ flashrom -p dummy:size=8388608,emulate=VARIABLE_SIZE -V
$ flashrom -p dummy:size=8388608,emulate=VARIABLE_SIZE
-r /tmp/dump.bin -V
$ head -c 8388608 </dev/urandom >/tmp/image.bin
$ flashrom
-p dummy:image=/tmp/image.bin,size=8388608,emulate=VARIABLE_SIZE
-w /tmp/dump.bin -V
also same as above with erase_to_zero=yes
Testing standard flow
$ flashrom -p dummy:emulate=W25Q128FV -V
$ flashrom -p dummy:emulate=W25Q128FV -r /tmp/dump.bin -V
$ head -c 16777216 </dev/urandom >/tmp/image.bin
$ flashrom -p dummy:image=/tmp/image.bin,emulate=W25Q128FV
-w /tmp/dump.bin -V
Testing invalid combination of programmer params (`init_data` fails
and prints error message which is WAI)
$ flashrom -p dummy:size=8388608 -V
-> init_data: size parameter is only valid for VARIABLE_SIZE chip.
$ flashrom -p dummy:emulate=VARIABLE_SIZE -V
-> init_data: the size parameter is not given.
$ flashrom -p dummy:emulate=W25Q128FV,erase_to_zero=yes -V
-> init_data: erase_to_zero parameter is not valid for real chip.
