The st,stm32-xspi compatible is defining the reg property with the register address and size at first index followed by the external memory base address and max allocated size. For the stm32N6 serie, xspi1 is addressing max 256 MBytes from 0x90000000 xspi2 is addressing max 256 MBytes from 0x70000000 Signed-off-by: Francois Ramu <[email protected]>

This PR is for fixing the #88404 for the XSPI compatible
It changes the way the "st,stm32-xspi-nor" compatible declares the external flash base address and size.
The "st,stm32-xspi" node, gives the external memory base address and maximum allocated space (in bytes):
The "st,stm32-xspi-nor" node, gives the external NOR device size in Bits through the
