Add R11e-5HacD, QCA9990, MT7615E, AR9827 to iwinfo
Backport a few commits from https://git.openwrt.org/?p=project/iwinfo.git;a=summary so a few Mikrotik cards will be no longer shown as generic in LuCI.
Requested on IRC by @neheb to have it included in OpenWrt 19.07.
Compile tested as I didn't have these cards to test.
