qcacld-3.0: Add support to optimize latency using pm_qos

Browse Source 
For Voice and Music (V&M) products, extreme latency optimization is
needed while playing music and discovery, higher power consumption
in this mode could be accepted. With CONFIG_WLAN_LL_MODE enabled,
when latency_level is set to ultra low via cfg80211 vendor command,
update request pm qos type PM_QOS_CPU_DMA_LATENCY to level
DISABLE_KRAIT_IDLE_PS_VAL to speed up CPU efficiency and irq response.
