Subject: [PATCH 12/17] media: atomisp: pci: make fw ver irci_stable_candrpv_0415_20150521_0458 work - 5/5

This is one of the patches which partially revert incompatible changes
in the current css version for ISP2401 (irci_ecr-master_20150911_0724)
back to irci_stable_candrpv_0415_20150521_0458.

Some `struct`s are `sizeof()`ed in sh_css_firmware.c file. So, I guess
issues will happen if these sizes are changed. Therefore, keep them the
same as css version irci_stable_candrpv_0415_20150521_0458 to make atomisp
work for firmware made for such css version since we don't have firmware
made for the current css version.

This patch removes the unnamed struct `shading` from
`struct sh_css_sp_pipeline` as well as its usage [1].

[1] added on updating css version to irci_master_20150701_0213

    ("atomisp2: css2401 and 2401_legacy-irci_master_20150701_0213")
