of: Add a new macro to declare_of for one parameter function returning a value
The macro OF_DECLARE_1 expect a void (*func)(struct device_node *) while the
OF_DECLARE_2 expect a int (*func)(struct device_node *, struct device_node *).
The second one allows to pass an init function returning a value, which make
possible to call the functions in the table and check the return value in order
to catch at a higher level the errors and handle them from there instead of
doing a panic in each driver (well at least this is the case for the clkevt).
Unfortunately the OF_DECLARE_1 does not allow that and that lead to some code
duplication and crappyness in the drivers.
The OF_DECLARE_1 is used by all the clk drivers and the clocksource/clockevent
drivers. It is not possible to do the change in one shot as we have to change
all the init functions.
The OF_DECLARE_2 specifies an init function prototype with two parameters with
the node and its parent. The latter won't be used, ever, in the timer drivers.
Introduce a OF_DECLARE_1_RET macro to be used, and hopefully we can smoothly
and iteratively change the users of OF_DECLARE_1 to use the new macro instead.
