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 polling_mode and subscr_index from
`struct virtual_input_system_stream_s` as well as its usage [1]. Note
that for subscr_index, only the definition were removed because it was
not used anywhere.
[1] added on updating css version to irci_master_20150701_0213
