qcacld-3.0: hdd: Add EGAP interface and ini configuration

qcacld-2.0 to qcacld-3.0 propagation

This change introduces 4 ini parameters to configure to firmware
    - gEenableEGAP:   forcely overwrite firmware feature capb
    - gEGAPInactTime: inactivity timeout value
    - gEGAPWaitTime:  wait timeout value before enter EGAP mode
    - gEGAPFeatures:  the feature flag firmware would support
        WMI_AP_PS_EGAP_F_ENABLE_PHYERR_DETECTION       0x1
        WMI_AP_PS_EGAP_F_ENABLE_PWRSAVE_BY_PS_STATE    0x2
        WMI_AP_PS_EGAP_F_ENABLE_PWRSAVE_BY_INACTIVITY  0x4

Integrate the hdd_wlan_kick_green_ap to execute the Green AP
and EGAP features, depending on the ini and also the tgt_cfg
capability flag,
