Renesas ARM based r8a7790 SoC update for v3.10

Browse source 
* Force architecture timer to be activated regardless of bootloader
   - This is necessary for the lager board to boot
 * Add second memory range to r8a7790 PFC device
   - This is in preparation for further PFC work.
     It should not break anything as it is not used yet.
