[flashrom] Optimized Erase Function Selection Algorithm Enabled by Default

[Aarya Chaumal]

Hi everyone,

I am excited to announce that the optimized erase function selection
algorithm is now enabled by default. It will optimally select the
erase functions according to the flash region to erase/write. This should
make using our application quicker and more convenient.

In case anyone experiences inexplicable behavior, the feature can be
disabled by doing the following change to the flashrom.c file and build
flashrom using make or meson.
```
-static bool use_legacy_erase_path = true;
+static bool use_legacy_erase_path = false;
```

Please let us know if you have any questions or encounter any issues. Bug
reports are welcome.
Aarya.
