boards: lpcxpresso55s69: use LMA adjustment for second core

Browse source 
Use LMA adjustment building dual core image with LPC55s69. The load
address adjustment allows the second core image to be flashed onto the chip
by the debugger, into the secure region of the LPC flash.

Additionally, remove the build dependency that was enforced by the SOC.
This requirement to build the secondary core image first can be enforced
by the project itself, instead of the core.
