arm: ip_k66f: Introduce board specific linker.ld file
This patch introduces linker.ld file specific for ip_k66f board.
It reuses the "common" linker script for other NXP SoCs with defined
NETWORK_RAM_SECTIONS() macro for explicit placement of network
interfaces on ip_k66f board.

As a result the eth0 (master DSA interface) is explicitly placed as the
first one (with the 'dts_ord_51' automatically assigned name) followed
by lan{123} interfaces (with 'dsa_slave_port' name assigned in
dsa_ksz8794.c).
After this patch network interfaces are explicitly placed in correct
order, so 'net_if_get_by_index()' will work correctly.
