The device-tree property to check secure and trusted boot state is
different for guests(pseries) compared to baremetal(powernv).
This patch updates the existing is_ppc_secureboot_enabled() and
is_ppc_trustedboot_enabled() function to add support for pseries.

as NX does not get faults on kernel addres

There are several reasons why a PCI capability read may fail whether the

return -EINVAL/PCIBIOS_BAD_REGISTER_NUMBER or PCIBIOS_DEVICE_NOT_FOUND
and *val is set to 0.
This behaviour if further
