util: Remove 'getpir' and 'mptable' tools

They create output in an obsolete form, are not actively maintained,
and the quality of the output is not better than randomly copy
pasting from other boards. These tools are no longer of any practical
value. remove them.

-ABOUT:
-
-This utility will help to create irq_table.c file, that is very hard to create
-manually, specialy when you are testing new motherboards, changing your
-hardware often, placing new cards, etc..
-
-USAGE:
-
-Steps
-1. make distclean;
-2. make getpir
-3. ./getpir
-
-   Will dump irq table to the file called irq_tables.c, ready to use with
-   coreboot. Just move the file to corresponding place in the coreboot tree.
-
-
-4. CHECKING CUSTOM irq_tables.c:
-
-   make checkpir
-   ./checkpir
-
-   checkpir.c Will verify the irq_tables.c, currently it only checks the
-   checksum. In case of wrong checksum, a good value is proposed, so you can
-   edit irq_tables.c manualy and replace checksum.
-
-
-Do not run make checkpir and ./checkpir directly because it needs to be linked
-to irq_table.o first.
