purism/librem13v1, librem13v2, liberm15v3: Fix EC LPC I/O port 

The LPC I/O ports for EC communication were not set properly,
causing ectool to fail to read the Index I/O from the EC.

The EC Index I/O is on port 0x380 and the LPC I/O port needs to be
decoded by the PCI device for it to be accessible.

Correct the value for the Librem 13v1, 13v2 and 15v3.
