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 2.4 GHz
and 5 GHz 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.

Because another patchset adding rtl8192du is based on this patch, I suggest
to send them as single one patchset.

I can do that, but Kalle will probably apply this patch long
before v2 of that patchset is ready.

Right. But next time you can send mutual dependent patches in a patchset, or
describe their dependency in cover letter. And, I prefer them in a patchset.
