So SPI_INTEL_SPI_PCI selects SPI_INTEL_SPI:

config SPI_INTEL_SPI_PCI
tristate "Intel PCH/PCU SPI flash PCI driver (DANGEROUS)"
depends on X86 && PCI
select SPI_INTEL_SPI

without checking that PLATFORM_INTEGRITY_DATA is set/enabled.

"select" does not follow any kconfig dependency chains, so when
PLATFORM_INTEGRITY_DATA is not enabled, this should be causing
a kconfig warning, which is not OK.
