usb: chipidea: Simplify Tegra DMA alignment code
The USB host on Tegra3 works with 32-bit alignment. Previous code tried
to align the buffer, but it did align the wrapper struct instead, so
the buffer was at a constant offset of 8 bytes (two pointers) from
expected alignment. Since kmalloc() guarantees at least 8-byte
alignment already, the alignment-extending is removed.
