soc/intel/braswell: increase LPEA fw allocation to 2MiB
Increase memory allocated for the LPEA firmware from 1MiB to 2MiB
to match Intel CHT reference code and fix Windows functionality.
Test: boot Windows on google/edgar, observe no error in Device Manager
for LPEA audio device due to BAR2 resource allocation.
