Devices that need to have their AOAC register enabled do have a delay before

a procedure that initializes all AOAC devices in a table and wait for all

coreboot's PCI resource allocator doesn't assign BAR1 for
Braswell's LPE device because it doesn't exist, but is
required by Windows drivers for the device to function.
Manually add the required resource via the existing
lpe_read_resources function, and marked it as IORESOURCE_STORED
so pci_dev_set_resources ignores it.
TEST: boot Windows 10 on google/edgar, observe that memory resources
are properly assigned to LPE driver for BAR1 and no error reported.

Add timestamps before and after the vBIOS load and after the vBIOS
run. This lets us see exactly how long it took to load it from the
ROM chip, and how long it takes to run.
BUG=b:64549506
TEST=Build & boot Grunt, see vBIOS load & initialization times.
