doc: add iomem kernel parameter for board inspector

Browse Source 
Without this ``iomem=relaxed`` kernel parameter, the generated board XML
is essentially the same as having ``--basic`` when executing the board
inspector, i.e. the ACPI namespace will not be parsed. The generated
board XML may still work, but some functionality (e.g. passthru of TPM
and other PCI devices that need INTx) will no longer work due to lack of
hardware information.
