Although designs may contain an ISP IP block, the camera might be a USB
camera. Because of this the ISP firmware is considered optional from
amdgpu. However if the firmware doesn't get loaded the hardware should
not be initialized.
Adjust the return code for early init to ensure the IP block doesn't go
through the other init and fini sequences. Also decrease the message
about firmware load failure to debug so it's not as alarming to users.

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:
