[PATCH V3 2/2] x86: IOSF: Change IOSF_MBI Kconfig to default y

["David E. Box" <david.e.box@linux.intel.com>]

From: "David E. Box" <david.e.box@linux.intel.com>

The IOSF Mailbox interface is an access mechanism used by multiple drivers to
communicate with key configuration registers on new Intel SOC platforms. The
interface is ubiquitous enough that we need to ensure the availability of the
driver in non-EXPERT configured x86 kernels.
