Amaury Pouly c7f897faa4 zen/zenxfi: always set EMI frequency to 130MHz 
The ZEN/X-Fi (STMP3700) don't handle memory frequency scaling really well, for
this reason we run it at a fixed frequency. That frequency was previously set
to 64Mhz because when the CPU run at its lowest frequency, we set the VDD voltage
to 0.975 V and on STMP3700, VDDD=VDDDMEM and this is too low to run EMI at 130Mhz.
This is not a good solution because under heavy load, running the EMI at 64Mhz
results in frame drops and a sluggish device. Thus we now run the EMI at 130Mhz
all the time now. To do so, increase the minimum VDD voltage to 1.275 V.
This may result is a decreased battery life on those targets but it will also
avoid all sorts of glictches and all the device to truly run at full speed.
