[PATCH] McBSP dependence for DSP on ARCH_OMAP1 is missing

Hi,

I've tried to compile an up-to-dated kernel tree configured for h3. I
got some errors due to the McBSP depends on OMAP_DSP if ARCH_OMAP1 is
set, as we can see at these lines from "arch/arm/plat-omap/mcbsp.c":

(...)
#ifdef CONFIG_ARCH_OMAP1
static void omap_mcbsp_dsp_request(void)
{
    if (cpu_is_omap15xx() || cpu_is_omap16xx()) {
        omap_dsp_request_mem();

(...)
#endif
(...)

So, I've made this minimal patch to deal with this problem. It worked
well for me. But I put, also, CONFIG_OMAP_DSP=y as default on h3 config
file to keep the OMAP_MCBSP as default too.

BR,

David Cohen
