Paul Walmsley e2ed89fc4e ARM: OMAP: add includes for missing prototypes
Several C files in arch/arm/mach-omap* and arch/arm/plat-omap declare
functions that are used by other files, but don't include the header
file where the prototype is declared.  This results in the following
warnings from sparse:

    arch/arm/mach-omap2/irq.c:114:5: warning: symbol 'omap_irq_pending' was not declared. Should it be static?
    arch/arm/mach-omap2/irq.c:186:13: warning: symbol 'omap2_init_irq' was not declared. Should it be static?

    arch/arm/mach-omap1/reset.c:11:6: warning: symbol 'omap1_restart' was not declared. Should it be static?

Fix by including the appropriate header files.
