qcacld-3.0: Replace typedef tSirWifiChannelInfo

The Linux Coding Style enumerates a few special cases where typedefs
are useful, but stresses "NEVER EVER use a typedef unless you can
clearly match one of those rules." The tSirWifiChannelInfo typedef
does not meet any of those criteria, so replace it (and the "tp"
variant) with a properly named struct.

In addition the Linux Coding Style frowns upon mixed-case names so
rename the members which are currently not compliant.
