fsp: Move fsp to fsp1_0

Prepare for FSP 1.1 integration by moving the FSP to a FSP 1.0 specific
directory. See follow-on patches for sharing of common code.

-	help
-	  The path and filename of the Intel FSP binary for this platform.
-
-config FSP_LOC
-	hex "Intel FSP Binary location in CBFS"
-	help
-	  The location in CBFS that the FSP is located. This must match the
-	  value that is set in the FSP binary.  If the FSP needs to be moved,
-	  rebase the FSP with Intel's BCT (tool).
-
-config ENABLE_FSP_FAST_BOOT
-	bool "Enable Fast Boot"
-	select ENABLE_MRC_CACHE
-	default n
-	help
-	  Enabling this feature will force the MRC data to be cached in NV
-	  storage to be used for speeding up boot time on future reboots
-	  and/or power cycles.
-
-config ENABLE_MRC_CACHE
-	bool
-	default y if HAVE_ACPI_RESUME
-	default n
-	help
-	  Enabling this feature will cause MRC data to be cached in NV storage.
-	  This can either be used for fast boot, or just because the FSP wants
-	  it to be saved.
-
-config MRC_CACHE_SIZE
-	hex "Fast Boot Data Cache Size"
-	default 0x10000
-	depends on ENABLE_MRC_CACHE
-	help
-	  This is the amount of space in NV storage that is reserved for the
-	  fast boot data cache storage.
-
-	  WARNING: Because this area will be erased and re-written, the size
-	  should be a full sector of the flash ROM chip and nothing else should
-	  be included in CBFS in any sector that the fast boot cache data is in.
-

-
-	  WARNING: This should be on a sector boundary of the BIOS ROM chip

-	  ERASED.
-
-config VIRTUAL_ROM_SIZE
-	hex "Virtual ROM Size"
-	default ROM_SIZE
-	depends on ENABLE_MRC_CACHE
-	help
-	  This is used to calculate the offset of the MRC data cache in NV
-	  Storage for fast boot.  If in doubt, leave this set to the default
-	  which sets the virtual size equal to the ROM size.
-
-	  Example: Cougar Canyon 2 has two 8 MB SPI ROMs.  When the SPI ROMs are
-	  loaded with a 4 MB coreboot image, the virtual ROM size is 8 MB.  When
-	  the SPI ROMs are loaded with an 8 MB coreboot image, the virtual ROM
-	  size is 16 MB.

-	default CBFS_SIZE
-	help
-	  This is the size of the cachable area that is passed into the FSP in
-	  the early initialization.  Typically this should be the size of the CBFS
-	  area, but the size must be a power of 2 whereas the CBFS size does not
-	  have this limitation.
-
-config USE_GENERIC_FSP_CAR_INC
-	bool
-	default n
-	help
-	  The chipset can select this to use a generic cache_as_ram.inc file
-	  that should be good for all FSP based platforms.
-
-config FSP_USES_UPD
-	bool
