Subject: [PATCH 12/32] phy: exynos: Use one define for enable bit
From: Krzysztof Kozlowski <krzk@...nel.org>
There is no need for separate defines for Exynos4 and Exynos5 phy enable
bit and MIPI phy reset bits. In both cases there are the same so
simplify it.
This reduces number of defines and allows removal of one header file.
