drm/amd/display: Wire up dcn10_dio_construct() for all pre-DCN401 generations

Description:
 - Commit b82f0759346617b2 ("drm/amd/display: Migrate DIO registers access
   from hwseq to dio component") moved DIO_MEM_PWR_CTRL register access
   behind the new dio abstraction layer but only created the dio object for
   DCN 4.01. On all other generations (DCN 10/20/21/201/30/301/302/303/
   31/314/315/316/32/321/35/351/36), the dio pointer is NULL, causing the
   register write to be silently skipped.

   This results in AFMT HDMI memory not being powered on during init_hw,
   which can cause HDMI audio failures and display issues on affected
   hardware including Renoir/Cezanne (DCN 2.1) APUs that use dcn10_init_hw.

   Call dcn10_dio_construct() in each older DCN generation's resource.c
   to create the dio object, following the same pattern as DCN 4.01. This
   ensures the dio pointer is non-NULL and the mem_pwr_ctrl callback works
   through the dio abstraction for all DCN generations.
