[PATCH v3 07/13] ARM: shmobile: R-Mobile: Use generic_pm_domain.attach_dev() for pm_clk setup

[Geert Uytterhoeven <geert+renesas@glider.be>]

Use the just introduced genpd attach/detach callbacks to register the
devices' module clocks, instead of doing it directly, to make it
DT-proof.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
