Memory set aside for the vpr_launcher partition.
Must match the size of the cpuapp_rram/cpuapp_mram partition which is deleted.
This to place the flpr app's code at the address found in the devicetree.

nrf54l15 does not match, is 188KiB in https://github.com/nrfconnect/sdk-zephyr/blob/3f337ca1170cd7aa9c4a62c1a9cce992e5caed90/dts/common/nordic/nrf54l15.dtsi which is 0x2f000 not 0x28000

There is nordic-flprsnippet that adds building of vpr_launcher.
It changes SRAM partitioning.

Value of 160k / 0x28000 is set here:
https://github.com/nrfconnect/sdk-zephyr/blob/main/snippets/nordic-flpr/soc/nrf54l15_cpuapp.overlay#L32

Not sure why it's done this way.
