arch/arm/rp2040: Silence "LOAD segment with RWX permissions" linker warnings

Browse Source 
This arch uses code relocation to SRAM through a XIP unit, so forcing segment
permissions manually in the linker script could create unforeseen issues.
A quick fix is setting the "--no-warn-rwx-segments" linker option just for
for the incriminated stage2 bootloader binary.
