Defining DEBUG should only be done in development.
So remove DEBUG.

Seems to only be used for printing the pr_debug() functions.

Btw, this removes the MTRR ranges output from dmesg - something which
we have had since forever. If you guys think it is still important for
debugging purposes, I can resurrect it by making all those pr_info.
This thing:
MTRR default type: uncachable
MTRR fixed ranges enabled:
00000-9FFFF write-back
A0000-BFFFF write-through
C0000-FFFFF write-protect
MTRR variable ranges enabled:
0 base 000000000000 mask FFFF80000000 write-back
1 base 000080000000 mask FFFFC0000000 write-back
2 base 0000C0000000 mask FFFFE0000000 write-back
3 disabled
4 disabled
5 disabled
6 disabled
7 disabled
