acpi: Add a debug option to print out tables in ACPICA compatible hex

Sometimes systems don't boot to the OS due to wrong ACPI tables.
Printing the tables in an ACPICA compatible format makes analysis of
ACPI tables easier.

The ACPICA format (acpidump, acpixtract) is the following:
"
FACS @ 0x0000000000000000
    0000: 46 41 43 53 40 00 00 00 E8 24 00 00 00 00 00 00  FACS@....$......
    0010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
    0020: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
    0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................

"

To achieve analyze ACPI tables capture the coreboot log between
"Printing ACPI in ACPICA compatible table" and "Done printing ACPI in
ACPICA compatible table". Remove the prefix "[SPEW ]  " and then call
'acpixtract -a dump' to extract all the tables. Then use 'iasl -d' on
the .dat files to decompile the tables.
