Subject: [PATCH v2] pseries: don't override CONFIG_PPC_PSERIES_DEBUG

eeh and pci_dlpar #undef DEBUG, but I think they were added before the
ability to control this from Kconfig. It's really annoying to only get
some of the debug messages from these files. Leave the lpar.c #undef
alone as it produces so much output as to make the kernel unusable.
Update the Kconfig text to indicate this particular quirk :)
