Add initialization and deinitialization sequence for CFR module.
CFR module will be initialized only when the following criteria passes,
* Enabled CFR support for the hardware through the
hardware param 'cfr_support'
* WMI service enabled for the CFR support
'WMI_TLV_SERVICE_CFR_CAPTURE_SUPPORT'
Also, provide a configuration option CONFIG_ATH11K_CFR to enable
CFR feature support during the compilation time.
CFR module initialization includes Direct Buffer(DB) ring initialization
where HW uses the DB ring buffers to copy CFR data to host.
Number of buffers and buffer size of the ring is based on the DB ring
capabilities advertised by the firmware through WMI service ready.
Also ring configurations are sent to firmware through
ath11k_dbring_wmi_cfg_setup().
