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.
