Subject: [PATCH v2] staging: rtl8188eu: Removed code valid for 5GHz

This patch removes support for channels > 14. That is from the TODO which
says:

	-find and remove remaining code valid only for 5HGz. Most of
	obvious ones have been removed, but things like channel > 14 still
	exist.

Signed-off-by: Bhaskar Singh <bhaskar.kernel@...il.com>

Changes in v2:
- Make the commit message more clearer.
- Rectify indentation as per Linux kernel coding style.
