This reverts commit 882164a4a928bcaa53280940436ca476e6b1db8e.

Above commit added "SSB = y" dependency to the wrong symbol
SSB_DRIVER_PCICORE_POSSIBLE and prevented SSB_DRIVER_PCICORE from being
selected when needed. PCI core driver for core running in clienthost
mode is important for bus initialization. It's perfectly valid scenario
to have ssb built as module and use it with buses on PCI cards.

This fixes regression that affected all *module* users with PCI cards.

As these patches fix regression/build error, I believe both should get
into 4.17.

How much confidence do we have that we don't need to end up reverting
patch 2 as well? I rather be pushing patch 2 to 4.18 so that there's
more time for testing and waiting for feedback.

Although I do not have the hardware to test the builds, I worked closely with the OP in the bug at b.r.c noted above. From that effort, it became clear what configuration variables were missing to cause the x86 failures. Patch 2 satisfies the requirement, and prevents the build problems found by the MIPS users. Both patches are needed in 4.17.
