snprintf can truncate the output fw filename if the isp ucode_prefix
exceeds 29 characters. Knowing ISP ucode_prefix is in the format
isp_x_x_x, limiting the size of ucode_prefix[] to 10 characters
to fix the warning.
Fixes the below warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_isp.c: In function 'isp_early_init':
drivers/gpu/drm/amd/amdgpu/amdgpu_isp.c:192:58: warning: 'snprintf'
output may be truncated before the last format character
[-Wformat-truncation=]
192 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s.bin", ucode_prefix);
