Replace all the single elements arrays with the element itself.
Pahole shows the same padding and alignment for x86 and arm in both
situations.
This fixes this cocci warning:

Replace the older style one-element array with a flexible array member.
There does not seem to be any allocation for this struct in the code, so
no more code changes are required.

Replace old style single array member, with flex array.
The struct is allocated, but it seems like there was an over allocation
error:
fw_buf = kmalloc(ALIGN(fw->size + sizeof(struct sms_firmware),
SMS_ALLOC_ALIGNMENT), GFP_KERNEL | coredev->gfp_buf_flags);
This change fixes this cocci warning:

Replace the old style single element array with a flex array. We do not
allocate this structure, so the size change should not be an issue.
This fixes the following cocci warning:

This field is never used, but if we remove it we would change the size
of the struct and can lead to behavior change. Stay on the safe side by
replacing the single element array with a single element field.

The struct hfi_session_get_property_pkt is always used to fectch a
single property. Make that explicit in the code and avoid a single
element array at the end of the struct.
This change fixes the following cocci warning:

plane_info is not a typical array, the data is not contiguous:
pinfo = (void *)pinfo + sizeof(*constr) * num_planes +
2 * sizeof(u32);
Replace the single element array with a single element field.

The single data array data[1] is only used to save the extradata_size.
Replace it with a single element field.

Replace the old style single element array at the end of the struct with
a flex array.
The code does not allocate this structure, so the size change should not
be a problem.
This fixes the following cocci warning:
