brcmfmac: remove obsolete i-scan and clean up related code.



e-scan has become the default scanning method. This patch removes
the i-scan related code and cleans up e-scan related code to be
always enabled.

This option enables the I-Scan method. By default fullmac uses the
new E-Scan method which uses less memory in firmware and gives no
limitation on the number of scan results.
