Subject: [PATCH 4.9 113/145] x86/platform: Add PCI dependency for PUNIT_ATOM_DEBUG

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit d689c64d189e43d782fec5649fb0afe303c5b3f9 upstream.

The IOSF_MBI option requires PCI support, without it we get a harmless
Kconfig warning when it gets selected by PUNIT_ATOM_DEBUG:

  warning: (X86_INTEL_LPSS && SND_SST_IPC_ACPI && MMC_SDHCI_ACPI && PUNIT_ATOM_DEBUG) selects IOSF_MBI which has unmet direct dependencies (PCI)

This adds another dependency to avoid the warning.
