dmaengine: loongson2-apb: Change GENMASK to GENMASK_ULL

Fix the following smatch static checker warning:

drivers/dma/loongson2-apb-dma.c:189 ls2x_dma_write_cmd()
warn: was expecting a 64 bit value instead of '~(((0)) + (((~((0))) - (((1)) << (0)) + 1) & (~((0)) >> ((8 * 4) - 1 - (4)))))'

The GENMASK macro used "unsigned long", which caused build issues when
using a 32-bit toolchain because it would try to access bits > 31. This
patch switches GENMASK to GENMASK_ULL, which uses "unsigned long long".
