[ Upstream commit c8931ef55bd325052ec496f242aea7f6de47dc9c ]
Struct uvc_frame and interval (u32*) are packaged together on
streaming->formats on a single contiguous allocation.
Right now they are allocated right after uvc_format, without taking into
consideration their required alignment.
This is working fine because both structures have a field with a
pointer, but it will stop working when the sizeof() of any of those
structs is not a multiple of the sizeof(void*).
Enforce that alignment during the allocation.
