From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

When CONFIG_COMMON_CLOCK is enabled, call rcar_gen2_clocks_init() in the
timer init function to initialize the common clock framework before
initializing the clock sources. This will take care of clock
initialization when the r8a779[01] boards will be switched to
multiplatform kernels.

(cherry picked from commit 4b5c211f9f93c3919f23c88d808a4eda104ec8b2)
(Queued by Simon Horman for v3.14 but not yet in Linus's tree)
