Subject: [PATCH 6/6] PM / devfreq: event: exynos-ppmu: Add the completion log
 of device registration

This patch just adds the simple log to show the PPMU device's registration
during the kernel booting.

For example on exynos4412-odroidu3 board as following:
[    1.845929] exynos-ppmu: new PPMU device registered 106a0000.ppmu_dmc0
[    1.848997] exynos-ppmu: new PPMU device registered 106b0000.ppmu_dmc1
[    1.853512] exynos-ppmu: new PPMU device registered 112a0000.ppmu_rightbus
[    1.860524] exynos-ppmu: new PPMU device registered 116a0000.ppmu_leftbus0
