[PATCH 1/3] clk: ignore of_device_ensure_probed error in clock lookup

[Lucas Stach <dev@lynxeye.de>]

For CLK_OF_DECLARE clocks there is no driver that is bound to the device,
so the lookup fails before even trying to find the provider, breaking
the parent_ready() logic used when initializing the declared providers.

Ignore the return code from of_device_ensure_probed to allow the lookup
to proceed as usual. If of_device_ensure_probed the lookup will also fail,
as no provider will be found.
