Makefile/mkconfig: read simple board configurations from boards.cfg

Instead of adding explicit build rules for each and every board to the
top level Makefile (which makes it grow and grow), we now provide a
simple default rule and extend the "mkconfig" script to read board
configurations from a plain text file (table), "boards.cfg".

For simple boards it is now sufficient to add a single line of text to
the "boards.cfg" file, no changes to the top level Makefile are needed
any more.

To make the table better readable, change the notation for unused
fields from "NULL" into "-".

+# Syntax:
+#	white-space separated list of entries;
+#	each entry has the following fields:
+#
+#	Targetname  Architecture  CPU  Boardname  Vendor  SoC
+#
+#	Unused fields can be specified as "-", or omitted if they
+#	are the last field on the line.
+#
+#	Lines starting with '#' are comments.
+#	Blank lines are ignored.
