drm/amdgpu: Fix ENOSYS means 'invalid syscall nr' in amdgpu_device.c

Browse Source 
ENOSYS should be used for nonexistent syscalls only, replace ENOSYS with
EOPNOTSUPP for reset handlers that are not implemented for respective ASIC.

WARNING: ENOSYS means 'invalid syscall nr' and nothing else
+       if (r == -ENOSYS)

WARNING: ENOSYS means 'invalid syscall nr' and nothing else
+       if (r == -ENOSYS)

And other following style fixes in amdgpu_device.c:

WARNING: Symbolic permissions 'S_IRUGO' are not preferred. Consider using octal permissions '0444'.
WARNING: Block comments should align the * on each line
WARNING: Missing a blank line after declarations
WARNING: braces {} are not necessary for single statement blocks
