media: staging: media: atomisp: fix stack overflow in init_pipe_defaults()
When building with clang, multiple copies of the structures to be
initialized are passed around on the stack and copied locally, using an
insane amount of stack space:
drivers/staging/media/atomisp/pci/sh_css.c:2371:1: error: stack frame size of 26864 bytes in function 'create_pipe' [-Werror,-Wframe-larger-than=]
Use constantly-allocated variables plus an explicit memcpy()
to avoid that.
