[PATCH] Makefile: Correct the rule removing old of-platdata files

[Simon Glass]

This makes use of makefile variables that don't exist anymore. Fix it and
also remove the object files in that directory.

Also add FORCE as a dependency as required by the if_changed macro.

Fixes 354d2324635 ("Makefile: Remove old of-platdata files before regenerating")
