help
Allows TLB driver to remap unused RAM - unused
being defined as memory ranging from linker script
defined "unused_l2_sram_start_marke" to end of RAM.
Note that unused memory will be powered off by
default. Disable this option if dynamically
managing memory, such as by usinga heap allocator.

This config is intended to support an external address
translation module if required for an SoC. Uses the
sys_mm_drv_page_phys_get() function from the system_mm API.
