When the EFS data is being packed, the pointer should be at EFS
header.
After that, it should be at body location.

We need to considering the case the EFS header is given as a relative
address and the other, body location, is given as an absolute one. So
we convert both of them to relative and check the validation.
For relative address case, the location should be between
0 and data size.

If ctx.address_mode is "physical", it will keep as "physical".
If ctx.address_mode is "relative to table", it will be changed as
"relative to BIOS".
Because the "current table" is the whole flash, the code worked well.

Since it actually depends on the SoC type whether the old PSP
directory table pointer or the new comboable PSP directory table
pointer is used in EFS, get this information from the SoC ID instead
of passing the comboable flag for the SoCs that need to use the new
comboable PSP directory table pointer.

Add support to write EFS and AMDFW body to separate files. This is done
through passing an optional --body-location parameter to the amdfwtool.
If that option is not passed, then EFS will be written in the same file
as the AMDFW body. This will help to keep the minimum data to be
loaded/mapped from CBFS in PSP verstage.
