media: gspca/gl860-mi1320/ov9655: avoid -Wstring-concatenation warning

Newer clang versions are suspicious of definitions that mix concatenated
strings with comma-separated arrays of strings, this has found real bugs
elsewhere, but this seems to be a false positive:

drivers/media/usb/gspca/gl860/gl860-mi1320.c:62:37: error: suspicious concatenation of string literals in an array initialization; did you
mean to separate the elements with a comma? [-Werror,-Wstring-concatenation]
        "\xd3\x02\xd4\x28\xd5\x01\xd0\x02" "\xd1\x18\xd2\xc1"
                                           ^
                                          ,
drivers/media/usb/gspca/gl860/gl860-mi1320.c:62:2: note: place parentheses around the string literal to silence warning
        "\xd3\x02\xd4\x28\xd5\x01\xd0\x02" "\xd1\x18\xd2\xc1"

Replace the string literals by compound initializers, using normal hex numbers.
