kernel_wireless_regdb: Add class for embedding regulatory data into older kernel
Linux kernels before v4.15, allowed to be compiled with static
regulatory database if it was put under net/wireless/db.txt.
Add kernel_wireless_regdb class which allows in such cases to embed the
wireless regulatory database directly in the Linux kernel during build
process.
Usage:
1. The class should be inherited by kernel recipe (e.g. in
linux-yocto_%.bbappend).
2. For Linux kernels up to v4.14, build kernel with CONFIG_EXPERT and
CONFIG_CFG80211_INTERNAL_REGDB.
