of: overlay: Fix kerneldoc warning in of_overlay_remove()

'*ovcs_id' causes a warning because '*' is treated as bold markup:

Documentation/devicetree/kernel-api:56: ../drivers/of/overlay.c:1184: WARNING: Inline emphasis start-string without end-string.

Fix this to use the normal '@' markup for function parameters.

 int of_overlay_remove(int *ovcs_id)

The change results in incorrect information. I am guessing that "@*ovcs_id" would not be valid syntax (I have not tried it). The changed version says that the pointer ovcs_id is changed to zero, but the actual action is to change the value pointed to by ovcs_id is changed to zero. Is there a valid syntax to say this?
