qcacld-3.0: Use QCS40X instead of QCS405 in config files

Use QCS40X instead of QCS405 in config files. Kernel defconfig files for
QCS405 and QCS403 has been separated recently, and the arch has been
changed between these two chips. But all QCS related features and changes
in cld should all be included, so use CONFIG_ARCH_QCS40X to replace
CONFIG_ARCH_QCS405.
