Subject: [PATCH] lib: Fix Kconfig indentation

Adjust indentation from spaces to tab (+optional two spaces) as in
coding style with command like:
	$ sed -e 's/^        /\t/' -i */Kconfig

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

---

Changes since v1:
1. Fix also 7-space and tab+1 space indentation issues.
