qcacmn: Add Roam reason and Roam sub-reason for Diag logging

The roam reason and roam sub-reason code sent and expected
reason codes at supplicant are diffent which results in
wrong interpretation of reason code.

Add roam reason and roam sub-reason code enum in order
to aid the converion from fw roam reason code to supplicant
understandable reason code.

+ * @DIAG_ROAM_REASON_CONGESTION: Roam triggered considering the connected
+ * channel or environment being very noisy / congested.
+ * @DIAG_ROAM_REASON_EXPLICIT_REQUEST: Roam triggered due to an explicit request
+ * from the user (user space).
+ * @DIAG_ROAM_REASON_BTM: Roam triggered due to BTM request frame received from

+ * @DIAG_ROAM_REASON_BSS_LOAD: Roam triggered due to the channel utilization
+ * breaching out the configured threshold.
+ * @DIAG_ROAM_REASON_WTC: Roam triggered due to Wireless to Cellular BSS

+ * certain threshold.
+ * @DIAG_ROAM_REASON_DISCONNECTION: Roam triggered due to
+ * deauthentication or disassociation frames received from the connected AP.
+ * @DIAG_ROAM_REASON_PERIODIC_TIMER: Roam triggered as part of the periodic
+ * scan that happens when there is no candiate AP found during the poor
+ * RSSI scan trigger.
+ * @DIAG_ROAM_REASON_BACKGROUND_SCAN: Roam triggered based on the scan
+ * results obtained from an external scan (not aimed at roaming).
+ * @DIAG_ROAM_REASON_BT_ACTIVITY: Roam triggered due to bluetooth
+ * connection is established when the station is connected in 2.4 Ghz band.
