Subject: [PATCH v2 06/11] mfd: intel-m10-bmc: Downscope SPI defines & prefix with M10BMC_SPI
Move SPI based board definitions to per interface file from the global
header. This makes it harder to use them accidently in the
generic/interface agnostic code. Prefix the defines with M10BMC_SPI
to make it more obvious these are related to SPI only.
Some bitfield defs are also moved to intel-m10-bmc-core which seems
more appropriate for them.
