boards: nordic: Rearrange ram0x regions.

Browse source 
The ram0x partitions seem to be not compliant with nRF54H20
architecture and it causes that in the application dts overlay file
it is difficult to extend cpuapp_ram0x_region without modifying
whole layout.

It is better to place cpurad_ram0x_region at the beginning at
2f010000 address and then cpuapp_ram0x_region right after that.
Thanks to that, if the application needs to have more than 256 kB
of RAM, in the application dts overlay file, a user can increase
cpuapp_ram0x_region size up to 2f0be000.
