pci: Rework pci_bar_addr()

This update makes pci_bar_addr() interface 64 bit BARs aware and
introduces a concept of PCI address translation.

An architecutre should implement pci_translate_addr() interface
in order to provide mapping between PCI bus address and CPU
physical address.

x86: vmx: better vm{launch,resume} error handling

This patch splits out entry error handling from other exit handling
since most tests don't expect entry errors and thus don't check the
conditions properly. Also enables tests for early entry errors (i.e.,
an entry_error_handler can return VMX_TEST_RESUME).

Consolidates and simplifies control flow. Now, vmx_run is the central
validation point for exit handler statuses rather than splitting the
responsibility between exit_handler and vmx_run.
