pass-hal: tm2: Add pass-resource5.conf for memory h/w device

This patch adds the new resource configuration for the memory h/w device
in order to handle the 'fault_around_bytes'[1] element.

The 'fault_around_bytes' indicates the number of bytes to be mapped
around the fault. If the value is low(e.g., 4096), it is able to
increase the empty memory on normal case. On the other hand,
if the value is high (e.g., 65536), it is able to improve
the performance by mapping the huge pages such as the app launching.
