soc/amd/common/psp_verstage: Always build unsigned PSP verstage 

Currently unsigned PSP verstage binary is copied from ELF file only when
required in amdfw*.rom. If a signed PSP verstage binary is supplied
while building amdfw*.rom, then it is dropped. Copy the unsigned PSP
verstage binary always so that it can be used for signing directly from
the CI build infrastructure instead of a locally built binary.

BUG=None
TEST=Build Skyrim BIOS image and ensure that the unsigned PSP verstage
is part of the build artifacts.

# Default CONFIG_PSP_VERSTAGE_FILE configuration requires psp_verstage.bin and the above
# build rule takes effect. Once CONFIG_PSP_VERSTAGE_FILE is overridden with signed PSP
# verstage, then psp_verstage.bin is not built. The following build rule ensures that the
# unsigned psp_verstage.bin is still built even when not used so that it can be used for
# signing purposes.
