qcacld-3.0: Memory optimize for QCS403 platform
Memory optimize for QCS403 platform, 1x1 chip. Reduce CE1 htt data
dest ring buffer from 512 to 256, reduce CE2 wmi dest ring buffer from
128 to 64, reduce CE9 & CE10 desg ring buffer from 512 to 64, disable
CE11 pktlog. Note: this change only affect specific WLAN build config for
extremely saving memory, for debug purose, there is another build
selecting default WLAN config for reference HW.
