qcacmn: Add support for remote channel width 320 MHz

Currently, We are using GET_STATION_INFO_REMOTE_CH_WIDTH
attribute for remote channel width which is using u8 for
storing the channel width info. However, for 320 MHz there
is a need to use u16 attribute to store the channel width
info.

This change is to preserve old interface and use new
interface to store u16 attribute for remote channel width.
