ath10k: enable 10.x firmware branch support

Since the WMI API has been added and we can detect from the
FW IEs what firmware variant we deal with, turn on support
for 10.x firmware branch in ath10k_wmi_attach().

ath10k: extend the max_scan time

It was observed few times, the artificial max_scan limit we
are using mainly to detect FW hangs, can be not enough for
instance while being associated and during heavy traffic.

What we do if the FW won't return with scan results within
the max_time time is a scan abort.

This is especially visible with 10.X fw which in combination
with dual band HW (scanning 32 channels) can end up with
hw_scan close to 10 seconds.

ath10k: remove ce_sendlist_send

It is completely pointless to keep this function
around. It doesn't do anything different than
ce_send except it introduces more overhead.
