[PATCH 3.3] OMAP4: PRM: fix build breakage when CONFIG_OF is not defined

[Luciano Coelho]

Since 3.3-rc1, prm44xx.c build breaks if CONFIG_OF is not set:

arch/arm/mach-omap2/prm44xx.c:41: error: 'OMAP44XX_IRQ_PRCM' undeclared here (not in a function)
make[1]: *** [arch/arm/mach-omap2/prm44xx.o] Error 1

This is because of a missing include, which is added indirectly if
CONFIG_OF is defined.  This problem was introduced in commit
2f31b51659c2d8315ea2888ba5b93076febe672b
