qcacmn: Add new attribute for roam reason
Currently, there is no attribute to get information for roam reason.
Atrribute QCA_WLAN_VENDOR_ATTR_ROAM_AUTH_REASON is added in
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH command to inform
the roam reason. An enum qca_roam_reason is defined for the valid
values of the QCA_WLAN_VENDOR_ATTR_ROAM_AUTH_ROAM_REASON.

+ *
+ * @QCA_ROAM_REASON_CONGESTION: Roam triggered considering the connected channel

+ * @QCA_ROAM_REASON_EXPLICIT_REQUEST: Roam triggered due to an explicit request
+ * from the user (user space).
+ *
+ * @QCA_ROAM_REASON_BTM: Roam triggered due to BTM request frame received from

+ *
+ * @QCA_ROAM_REASON_BSS_LOAD: Roam triggered due to the channel utilization
