x86: Add Kconfig to disable early bootblock postcodes

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).
