Add Device Trees for Realtek RTD1195 SoC and MeLE X1000 TV box.

Reuse the existing RTD1295 watchdog compatible for now.

Reviewed-by: Rob Herring <robh@kernel.org>
[AF: Fixed r-bus size, fixed GIC CPU mask, updated memreserve]
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
 v2 -> v3:
 * Fixed r-bus size in /soc ranges from 0x1000000 to 0x70000 (James)
 * Adjusted /memreserve/ to close gap from 0xa800 to 0xc000 for full 0x100000
 * Changed arch timer from GIC_CPU_MASK_RAW(0xf) to GIC_CPU_MASK_SIMPLE(2)
   squashed from RTD1395 v1 series
 
 v1 -> v2:
 * Dropped /memreserve/ and reserved-memory nodes for peripherals and NOR (Rob)
 * Carved them out from memory reg instead (Rob)
 * Converted some /memreserve/s to reserved-memory nodes
