6.1-stable review patch. If anyone has any objections, please let me know.

commit de4d4be4fa64ed7b4aa1c613061015bd8fa98b24 upstream.
Different channels have different TX power settings. rtl8192de is using the TX power setting from the wrong channel in the 5 GHz band because _rtl92c_phy_get_rightchnlplace expects an array which includes all the channel numbers, but it's using an array which includes only the 5 GHz channel numbers.
Use the array channel_all (defined in rtl8192de/phy.c) instead of the incorrect channel5g (defined in core.c).
Tested only with rtl8192du, which will use the same TX power code.
