wlan: cld: Add CLD driver configuration to Kconfig for APQ8084

The WLAN CLD driver depends on WEXT, NL80211 TESTMODE and PCI
support in the kernel. So add a CLD driver configuration
CONFIG_CLD_LL_CORE for qca6714 that selects WEXT and NL80211
Testmode support and sets the dependencies on PCI, MSI and PCIE.
Also add the CLD config to APQ8084 default kernel config.
