Michał Mirosław 03984e24db usb: chipidea: Simplify Tegra DMA alignment code
[ Upstream commit 2ae61a2562 ]

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.

Fixes: fc53d52790 ("usb: chipidea: tegra: Support host mode")
