Attach psp(4) version 1.
Some AMD CPUs come with an older platform security processor. It
is detectet by PCI Id and has different register offsets. Move the
dynamic register offsets into psp_softc. The PCI attach code is
now in a separate psp_pci.c file and detects the version of the psp
along with the ccp. The attach code is more verbose to display
where problems might occur. Now the ccp_wait() has 2 seconds
timeout, both for polling and interrupt. Also prevent a useless
bus_space_read_4().

Avoid ccp error message if SEV-ES is missing.
PSP is optional to ccp(4). Thus if PSP attachment fails (e.g.
interrupt can not be set up), do not unmap IO space. It will still
be needed by ccp(4).

be needed by ccp(4). Nonetheless, disestablish interrupt handler
if PSP attachment fails.
Another tweak: If PSP can not be initialized, there's no need to
actually flush caches (wbinvd) on all CPUs.
Cleanup dmesg output and make it more precise.
