Intel based boards: Use tab instead of spaces to align comment in DSDT

Mainboards using `COREBOOT` as their OEM Table ID in their DSDT
header were copied from the same source and therefore had spaces
instead of a tab to align that comment for that header field. These
are mostly Intel based  boards.

Fix that in accordance with the coding style [1].
