2016-06-21intel/apollolake: Enable SPI properly in bootblock and ramstageFurquan Shaikh
Bootblock: - Temporary BAR needs to be assigned for SPI device until PCI enumeration is done by ramstage which allocates a new BAR. - Call spi_init to allow bootblock/verstage to write/erase on flash. Ramstage: - spi_init needs to run in ramstage to allow write protect to be disabled for eventlog and NVRAM updates. This needs to be done pretty early so that any init calls(e.g. mainboard_ec_init) writing to flash work properly. Verified with this change that there are no more flash write/erase errors for ELOG/NVRAM.

On apollolake the boot media layout is different in that the traditional "BIOS" region contains another data structure with the boot assets such as CSE firmware, PMC microcode, CPU microcode, and boot firmware to name a few. There's also a sort of recovery mechanism where there is a second data structure with similar contents halfway through the "BIOS" region. This second structure is referred as the logical boot partition 2 (LBP2), and it's optionally employed. Add support for writing the LBP2 to a specified FMAP region to accommodate platforms which require it.
