[PATCH] OPP: debugfs: Fix warning with W=1 builds

[Viresh Kumar]

We currently get the following warning:

debugfs.c:105:54: error: '%d' directive output may be truncated writing between 1 and 11 bytes into a region of size 8 [-Werror=format-truncation=]
                 snprintf(name, sizeof(name), "supply-%d", i);
                                                      ^~
debugfs.c:105:46: note: directive argument in the range [-2147483644, 2147483646]
                 snprintf(name, sizeof(name), "supply-%d", i);
                                              ^~~~~~~~~~~
debugfs.c:105:17: note: 'snprintf' output between 9 and 19 bytes into a destination of size 15
                 snprintf(name, sizeof(name), "supply-%d", i);

Fix this and another potential issue it by increasing size of the arrays.
