Signed-off-by: franciscofranco <franciscofranco.1990@gmail.com>
arch: config: added personal ak_bacon_defconfig
ak-bacon-build: switch to ak_bacon_defconfig
ak_bacon_defconfig: enabled CPU_VOLTAGE_CONTROL
ak_bacon_defconfig: disable LOCALVERSION
ak_bacon_defconfig: disable GOV_POWERSAVE and GOV_USERSPACE
ak_bacon_defconfig: set default DEADLINE
deadline: Allow 0ms deadline latency, increase the read speed

Change a timer compare from after to after-equals, thus allowing
0 timeout and making deadline schedule FIFO.
