[Edward O'Callaghan (Code Review)]

Attention is currently required from: Angel Pons, Anastasia Klimchuk.

Hello build bot (Jenkins), Angel Pons,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/flashrom/+/69133

to look at the new patch set (#4).

Change subject: tree/: Convert flashchip erase_block func ptr to enumerate [ALT]

tree/: Convert flashchip erase_block func ptr to enumerate [ALT]

This forges the way for flashchips.c to be pure declarative
data and lookup functions for dispatch to be pure. This
means that the flashchips data could be extracted out to
be agnostic data of the flashrom code and algorithms.
