[Rocky Phagura (Code Review)]

Hello Subrata Banik, build bot (Jenkins), Jonathan Zhang, Angel Pons, Subrata Banik, Andrey Petrov, Patrick Rudolph,

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

to look at the new patch set (#4).

Change subject: drivers/intel/fsp2_0: Change boot state notification

drivers/intel/fsp2_0: Change boot state notification

Change boot state notification of FSP to before payload is loaded into
memory.
Currently the flow is as follows:
1.	Load payload into memory
2.	Notify FSP of boot state init
3.	Jump to payload code

This patch changes the flow to:
1.	Notify FSP of boot state
2.	Load payload into memory
3.	Jump to payload code

This prevents code corruption of payload.  At this stage of boot, there
is no concept of memory management, therefore FSP can use any memory it
needs. After making these changes, Tianocore payload is able to load
properly where previously its memory was getting corrupted.

TEST=build for Tiogapass platform under OCP mainboard and select
Tianocore payload.  Boot the system and ensure target OS loads.
