[PATCH v4 2/8] clk: samsung: change scope of samsung clock lock to global

[Thomas Abraham]

From: Thomas Abraham <thomas.ab at samsung.com>

Access to samsung clock lock is required to support newer samsung specific
clock types. So change the scope of the samsung clock lock to global. And
prefix 'samsung_clk_' to the existing name of the lock to prevent name space
pollution.
