WiFi: Update get/set of PreambleType param

Browse source 
Short preamble is handled in tr181 as radio parameter
with three possible values: long, short, auto.
Openwrt option short_preamble to store that information is
set per interface and has only two values 0,1.
Because of this difference we loose auto value.

Set PreambleType param for radio will cause setting
that value to all interfaces created on that radio.
Get PreambleType will return "short" when at least
one interface has it set to short, "long" will be returned
when all interfaces have preamble set to long.
