qcacld-3.0: Properly check max supported EHT bandwidth

Per 11BE Spec, only 320 MHz support in 6 GHz is defined in EHT
PHY capabilities. Therefore when deciding max target supported
EHT bandwidth, 320 MHz support is first checked using target
advertised EHT phy caps. If 320 MHz is not supported, fall back
to VHT channel width supported, which includes 160 MHz and 80 MHz.
