mb/hp: Add HP EliteBook Folio 9480m

The code is based on autoport, with necessary modifications.

This laptop uses SMSC MEC1322 embedded controller, but the EC
interface is the same as the EliteBook laptops of previous generations
that use KBC1126 EC. So it still uses ec/hp/kbc1126, but does not need
EC firmware inserted into CBFS. We also need to leave the end of the
OEM flash content untouched, so the default ROM size is set to 12MiB
instead of 16MiB, and we need to modify the IFD when flashing.

Thanks to persmule for providing the laptop and pointing out how to
program the system flash chip of it.
