qcacld-3.0: Add support for adaptive 11r

Adaptive 11r feature that enables the AP to support FT-AKM
without configuring the FT-AKM in the network. The AP will
advertise non-FT akm with a vendor specific IE having Adaptive
11r bit set to 1 in the IE data. The AP also advertises the
MDE in beacon/probe response.

The STA should check the adaptive 11r capability if the AP
advertises MDE in beacon/probe and adaptive 11r capability in
vendor specific IE.  If adaptive 11r capability is found,
STA should advertise the FT equivalent of the non-FT AKM.

Introdue a compile time flag WLAN_ADAPTIVE_11R_ENABLED to
enable/disable adaptive 11r support.

If the AP is adaptive 11r capable, set the is_adaptive_11r_ap
flag in bss descrtiptor. This flag will be sent in join request
and populated to pe_session. Also mark the CSR session as
adaptive 11r session based on this flag.

Add changes to check for the adaptive 11r service capability
advertised by firmware. If the host driver connects to adaptive
11r AP, enable RSO only if the firmware advertises adaptive
11r capability, else RSO should be disabled.

If the connection is adaptive 11r connection and if the adaptive
11r ini is enabled, set the adaptive_11r flag in
wmi_roam_11r_offload_tlv_param sent over the wmi command
WMI_ROAM_SCAN_MODE to the firmware. This will enable firmware to
filter the adaptive 11r AP from roam scan results.
