[PATCH] rockchip: rk3288: syscon: use per-driver of_match tables

[Rudi Heitbaum]

The OF_PLATDATA section shares a single rk3288_syscon_ids[] table across
four drivers, pointing each driver at its entry via pointer arithmetic:

  .of_match = rk3288_syscon_ids + 1,  /* grf  */
  .of_match = rk3288_syscon_ids + 2,  /* sgrf */
  .of_match = rk3288_syscon_ids + 3,  /* pmu  */

dtoc's src_scan.py parses driver source files to build of-platdata but
does not evaluate pointer arithmetic, so each suffix triggers:

  Warning: unexpected suffix ' + N' on .of_match line for compat
  'rk3288_syscon_ids'

Replace the shared-table-with-offset pattern with small per-driver
tables, eliminating the three build warnings.
