I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

Change subject: mainboard/ocp/monolake: Hide IIO root ports before memory init

mainboard/ocp/monolake: Hide IIO root ports before memory init

It turned on some SKUs FSP hangs in Notify stage if IIO root ports are
disabled after MemoryInit. To address that hide IIO root ports earlier
in romstage.

TEST=the patch was ran on affected HW and success was reported
