mach-ux500/devices-db8500: add more records to db8500_freq_table
LiveOPP: improve undervolting and extended frequencies stability
LiveOPP: more changes in liveopp logic
LiveOPP: Set voltage for freq <= 400MHz to 0x12

if phone's firmware uses this voltage by default, so can we...
LiveOPP: lower voltages for 500MHz and 900MHz
LiveOPP: increase 1250MHz real freq to 1248MHz
mach-ux500/suspend: enable arm khz qos on suspend

The problem of setting minimal cpu freq is unsolved anyway and it
makes suspend quicker
LiveOPP: debugfreq table init
