qualcommax: make header length configurable on Build/mstc-header

Browse source 
I-O DATA WN-DAX3000GR has a MSTC (Mitra Star Technology Corp.) specific
header with a different length than ELECOM WRC-X3000GS2.
Make the header length configurable by parameterizing on
Build/mstc-header.

- WRC-X3000GS2: 0x400
- WN-DAX3000GR: 0x480
