hw/dma/omap_dma: Fix bugs with DMA requests above 32
The drqbmp field of struct soc_dma_s is a uint64_t; however several
places in the code attempt to set bits in it using "(1 << drq)",
which will fail if drq is large enough that the 1 bit gets shifted
off the top of a 32 bit integer. Change these to "(1ULL << drq)" so
that the promotion to 64 bit happens before the shift rather than
afterwards.
