Revert "kernel: create firmware partition from MyLoader partition parser"

This reverts r38197.

The automatically created firmware partition includes
the partition_table partition. Apart from the partition
table, this partition contains sensitive data on some
Compex devices which data can be destroyed when the
firmware partition gets modified. Revert the change to
prevent that.
