CID 1488814: Uninitialized variables (UNINIT)
Commit c66ea98 introduced an issue after static analysis on merge.
Because every APIC is associated with a CPU, this did not result in
any issues at runtime but should be fixed/cleaned up. Now, the path
name is initialized to null.
Fixes: Coverity CID 1488814, commit c66ea98
TEST=Built on brya

Amdfwtool creates AMD firmware images however there is currently no way
to get information from an existing image. This commit adds amdfwread to
support that functionality. At the moment only reading PSP soft fuse
flags is supported. Example usage: `amdfwread --soft-fuse bios.bin`,
example output: `Soft-fuse:0x400000030000041`.

in diagnostics and understanding of S0ix entry failure.
Values were derived from Intel document 595644 (rev 0.45) and
the ADL FSP sample ASL.
This implementation adds support for ADL. Other SoC's could be

The makefiles don't like cbfs file names with spaces in them so update
the file name with '_' instead of spaces. To keep the master header at
the top of cbfs, add a placeholder.
This removes the need to handle the cbfs master header in cbfstool.
This functionality will be dropped in a later CL.
On x86 reserve some space in the linker script to add the pointer.
On non-x86 generate a pointer inside a C struct file.
As a bonus this would actually fix the master header pointer mechanism
on Intel/APL as only the bootblock inside IFWI gets memory mapped.
