[M] Change in flashrom[master]: drivers/: Make 'fallback_{un}map' the default unless defined

[Edward O'Callaghan (Code Review)]

Attention is currently required from: Edward O'Callaghan.

Hello build bot (Jenkins), Thomas Heijligen, Jonathon Hall, Nikolai Artemiev, Peter Marheine,

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

https://review.coreboot.org/c/flashrom/+/67404

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

Change subject: drivers/: Make 'fallback_{un}map' the default unless defined
......................................................................

drivers/: Make 'fallback_{un}map' the default unless defined

Drop the explicit need to specify the default 'fallback_{un}map'
callback function pointer. This is a reasonable default for
every other driver in the tree with only a select few exceptions.

Thus this simplifies driver development and paves way
to remove the 'programmer' global handle.
