Tony Lindgren 741e3a89de omap: Use separate init_irq functions to avoid cpu_is_omap tests early
This allows us to remove cpu_is_omap calls from init_irq functions.
There should not be any need for cpu_is_omap calls as at this point.
During the timer init we only care about SoC generation, and not about
subrevisions.

The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call.

* Modified from board-innovator1510.c
*
* Code for generic OMAP board. Should work on many OMAP systems where
* the device drivers take care of all the necessary hardware initialization.
* Do not put any board specific code to this file; create a new machine
* type if you need custom low-level initializations.
