The addresses and their modes should now all be correct and we can
therefore treat the case where `addr` and `mode` do not match as an
actual error.

There is no need to treat the APOB_NV binary special anymore, as
the mode and address should now always match for the APOB_NV address.
Since phoenix SOC generation this code even errors out on VBOOT
platforms, because APOB_NV address is actually a BIOS relative address.

FMAP should not contain information about the memory map.
Done with the following command:
"find -name \*.fmd -exec sed -i 's/\(FLASH\).* \(.*\) /\1 \2 /' {} \;"
for AMD:
All addresses that amdfwtool expects as command line parameter have the
ADDR_REL_BIOS (flash address) address_mode setting. One exception is
the *_FW_A_POSITION and *_FW_B_POSITION addresses. But amdfwtool checks
if memory or flash addresses are passed and converts accordingly. So
changing the address from memory -> flash doesn't matter for the
resulting binary.
Since commit 41a162b7a8 ("soc/amd/phoenix/Makefile.inc: Pass APOB_NV
address as offset") and therefore since phoenix SOC, APOB_NV is passed
as flash offset. But before that the memory ABL always assumed a MMIO
address (no matter the address_mode) so we need to add a little quirk
for that.
tested: boot glinda based mainboard and also check that memory training
is still cached successfully in APOB_NV.

Upcoming AMD SoCs use recovery A/B layout. Update amdfwread tool to
handle it.
Also add a generic read_header function to read different header types.

* AMD_ADDR_PHYSICAL refers to physical address in the memory map
* AMD_ADDR_REL_BIOS is relative to the start of the BIOS image
* AMD_ADDR_REL_TAB is relative to the start of concerned PSP or BIOS
tables
Update the relative_offset implementation accordingly. Though
AMD_ADDR_REL_SLOT is defined it is not used. Removing that to simplify
the relative_offset implementation so that it can be used for both PSP
and BIOS firmware tables. Hence update the relative_offset function
signature as well.

index I/O argument to getopt_long is not the index to argv. Instead it
is an index into the optlong array corresponding to the parsed option.
Also getopt() uses a global variable optind to track the index of the

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`.
BUG=b:202397678
TEST=Ran amdfwread and verified that it correctly reads the soft fuse
bits, verified that built AMD FW still boots on DUT
