Since Volteer also uses the CSE Lite SKU and the cr50, it is subject
to a problem where old cr50 FW will not be able to properly detect an
SoC reset, so the reset on cold boots caused by the CSE Lite RO->RW
jump should instead get an assist from the EC, which can perform a
full cold reset.
BUG=b:162977697
TEST=Verify EC performs the cold reset

The AM335X is a SoC, so should be in the soc tree.
This moves all the existing am335x code to soc/ and updates any
references. It also adds a soc.c file as required for the ramstage.

Switch from locating the AMD firmware in the RW_A &
RW_B regions with their hardcoded locations to using CBFS to find
them. They still need to be at the hardcoded locations so that we
can set the location inside the binary, but instead of just setting
the pointer directly to them, we now search for them with cbfs.

In CB:44488 the cbmem addition was re-filling the object

that oversight. The side effect from the previous implementation

GPP_A19(DP_HPD1) and GPP_A20(DP_HPD2) were configured native function
(NF1) without internal pull-down which wrongly presents HPD interrupts.
DP_HPD had been removed for EVT design as those events are through eSPI.
This change configures GPP_A19 and GPP_A20 to be no connection and
disables DdiPort1Hpd and DdiPort2Hpd.

* Change smm_module_params' cpu to size_t as 'push' is native integer
* Drop to protected mode after c handler
NOTE: This commit does NOT introduce a new security model. It uses the
same page tables as the remaining firmware does.
This can be a security risk if someone is able to manipulate the
page tables stored in ROM at runtime. USE FOR TESTING ONLY!
