Commit c0745129 (imx-esdhc: update devices registration) renamed
MX35_INT_MMC_SDHC2 to MX35_INT_ESDHC2 which broke expansion of the
MXC_INT_MMC_SDHC2 macro.
As  (the only user of MXC_INT_MMC_SDHC2) is only used on
mx31 use the MX31 prefixed symbol to define its resources.  Moreover to
reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC
prefixed symbols are removed.

i.MX35 CPUs marked with "MCIMX357CJQ5C M99V CTHA0943B" are coming with bogus
L2 cache settings. If these settings are kept unmodified prior enabling the L2
cache the CPU runs amok immediately when its enabled.

This fix should not hurt already working CPUs, as they are using the written
register value already.

Its currently unknown if its possible to detect the production lot from the
software to fix only affected CPUs.

Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX.  The structs holding the actual data
are placed in .init.constdata and so don't do much harm.  Compared to
the previous approach this reduces code size to call imx_add_spi_imx.
