sanitycheck: update section names in size calculator
sanitycheck: update section names in size calculator

Commit 8d7bb8ffd8faba73628e18e4651e20896da9751e refactored
device structures which changed some of the linker sections:
"devconfig" was removed, and "devices" was added. However,
the list in sanitycheck's size calculator was not updated,
which results in sanitycheck complaining about unrecognized
sections when doing footprint.

Also, a few sections have been renamed (with added suffix
"_area") due to introduction of Z_ITERABLE_SECTION_RAM/ROM
macros. There are also some missing section names.

Fixes the issue by adding the missing sections names, and
updating existing ones.
