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

Drop the explicit need to specify the default 'fallback_{un}map'
callback function pointer from the 'programmer_entry' struct.
This is a reasonable default for every other driver in the tree
with only a select few exceptions [atavia, serprog, dummyflasher
and internal].

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