Subject: [PATCH 2/2] media: atomisp: Fix Wformat-truncation warning

Gcc8 is convinced that we do not have enough space in dot_id_input_bin.
Extend the variable 17 bytes. It is just used for debugging.

drivers/staging/media/atomisp/pci/runtime/debug/src/ia_css_debug.c:1336:9: warning: '(pipe' directive output may be truncated writing 5 bytes into a region of size between 1 and 74 [-Wformat-truncation=]
