ath10k: read calibration data from Device Tree

This patch adds support for reading calibration data from Device Tree.
It looks for the calibration data in Device Tree if it can't find it
in a file. If there's no node in Device Tree, ath10k will try to find the
calibration data from OTP.

The node for the calibration data should be defined like this:

pci {
        pcie@0 {
                reg = <0 0 0 0 0>;
                #interrupt-cells = <1>;
                #size-cells = <2>;
                #address-cells = <3>;
                device_type = "pci";

                ath10k@0,0 {
                        reg = <0 0 0 0 0>;
                        device_type = "pci";
                        qcom,ath10k-calibration-data = [ 01 02 03 ... ];
                };
        };
};

ath10k: clean up error handling in ath10k_core_probe_fw()

Use the error handling style preferred in ath10k. Makes it easier to add
ath10k_init_firmware_features() function in the next patch.

ath10k: create ath10k_core_init_features()

It's easier to manage firmware version differences when we configure them in
one place. Rename ath10k_core_init_max_sta_count() to
ath10k_core_init_firmware_features() and start moving most of the firmware
version ("features") handling to that function.

ath10k: add ATH10K_FW_IE_WMI_OP_VERSION

Instead of using feature flags, add new 32 bit variable for managing different
WMI versions. This makes it firmware interface tests a bit less convoluted,
especially when we add one more interface.

ath10k: introduce wmi ops

Since the 10.x fw branch support was introduced it
became apparent ath10k will need to be able to
deal with different fw ABIs eventually.

The patch creates an abstraction for dealing with
command and event structures across different ABIs
and mostly gets rid of the
ATH10K_FW_FEATURE_WMI_10X flag usage.

ath10k: implement wmi-tlv backend

Latest main firmware branch introduced a new WMI
ABI called wmi-tlv. It is not a tlv strictly
speaking but something that resembles it because
it is ordered and may have duplicate id entries.

This prepares ath10k to support new hw.

ath10k: add new wmi interface of NF cal period

Introduce a new wmi interface controls noise floor (NF) calibration
period via debugfs as firmware has introduced it on v10.2.

It allows users to modify frequency of NF calibration in millisecond
and changes RSSI reporting frequency consequently.
Short calibration period will trigger more frequent NF calibration,
so that RSSI reported in receive frames is more realistic.

Till now calibration was done at 30 seconds.
