This looks very promising! A few comments just about things I noticed. More offline now...

Just a small remark for a more pythonic string composition:

Just as a remark for later: this map should be loaded/compiled/supplied in the head script, and then handed to the Transformation as an argument.

Again a remark for later, and I know that this doesn't apply in your use case but would be a requirement for integration into the main branch. So, I'm pointing this out here:
Transformations are intended to be written in a way that allows to instantiate them once and then apply them to an arbitrary number of subroutines. This information is local to one routine but currently it lives on the transformation object. Later, we should consider making these local variables in the transform_subroutine and, where necessary, have methods update or return them.

dcl = ir.VariableDeclaration(

I would recommend using the following pattern to add the relevant declarations:
routine.variables += tuple(v[1] for v in self.routine_map_derived.values())

raise NotImplementedError("This type isn't implemented yet")

# Creating the pointer on the field api object : YL%FA, YL%F_A...
if routine.variable_map[var.name_parts[0]].type.dtype.name=="MF_PHYS_SURF_TYPE":

Just as a remark: Using routine.variable_map repeatedly can be costly, because it compiles the map everytime from the variable declarations. In a routine like this, it's recommended to cache this at the top of the routine as variable_map = routine.variable_map and then use that local copy.
