[PATCH v3 3/4] clk: mvebu: armada-37xx-tbg: fill the device entry when registering the clocks

[Miquel Raynal]

So far the clk_hw_register_fixed_factor() calls are not providing any
device structure. While doing so is harmless for regular use, the
missing device structure may be a problem for suspend to RAM support.

Since, device links have been added to clocks, links created during
probe will enforce the suspend/resume orders. When the device is
missing during the registration, no link can be established, hence the
order between parent and child clocks are not enforced.

Adding the device structure here will create a link between the 4 TBG
clocks (registered by this driver) and:
* their parent clock: XTAL,
* their child clocks: several 'periph' clock.
