Subject: [PATCH] tcl/target: Add support for Nordic nRF54L series

The RISC-V coprocessor is currently not supported. It is attached to the
DAP via AP#2 but the AP implementation is unknown.

The nRFL54L series uses resistive RAM (RRAM) as non-volatile memory
which can be programmed directly. Since it does not fit in the current
flash memory infrastructure of OpenOCD there is no NVM support so far.
