wifi: rtlwifi: rtl8192de: Fix 5 GHz TX power

Browse Source 
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.
