x86: Add Kconfig to disable early bootblock postcodes

Hardware / Coreboot - Martin Roth [google.com] - 18 November 2015 17:16 UTC

The Intel cave creek chipset needs to have port 80 routing configured before any post codes can be sent to port 80h. Sending post codes out before the routing is done will hang the system.

This patch allows us to disable the first couple of post codes that go out before the routing can be configured.

The Kconfig symbol is selected by the cave creek chipset (fsp_i89xx).
