xf86Cursor: Use PRIME master xf86CursorScreenRec::HotX/Y for slaves

Browse Source 
xf86CursorScreenRec::HotX/Y contain 0 for PRIME slave screens.

Fixes incorrect HW cursor position on PRIME slave screens.

Also hoist the hotspot translation out from xf86ScreenSet/MoveCursor to
xf86Set/MoveCursor, since the hotspot position is a property of the
cursor, not the screen.

v2:
* Squash patches 1 & 2 of the v1 series, since it's basically the same
  problem
* Use the master screen's xf86CursorScreenRec::HotX/Y instead of
  CursorRec::bits->x/yhot, since CursorRec::bits can be NULL (Hans de
  Goede)
