dummyflasher: add SR2 and SR3 emulation harness

Prepare everything for emulating SR2 and SR3 for chips that have it.

This is needed for accessing SRP1 and WPS bits which are involved in
write protection. The emulated register doesn't affect anything yet
and will be tested by write-protection tests.

TEST=check how input value affects status registers of emulated chip

flashrom -V -p dummy:emulate=W25Q128FV,spi_status=0x12 |
        grep 'Initial status register'
flashrom -V -p dummy:emulate=W25Q128FV,spi_status=0x1234 |
        grep 'Initial status register'
flashrom -V -p dummy:emulate=W25Q128FV,spi_status=0x123456 |
        grep 'Initial status register'

Mind that at this point there are no chips that emulate more than one
status register.
