mb/amd/majolica: Disable IO ports 0x60/0x64
I suspect there is additional initialization required to enable the
8042 keyboard controller on the EC. By removing the range we no longer
encounter long 20 second delays when reading the IO ports. Since
depthcharge polls the IO ports it makes it seem like depthcharge locked
up.
BUG=b:182100027
TEST=Boot majolica with depthcharge to OS
