Boot: HS-FS ROM applies debug access restrictions to all address space covered by the efuse controller firewall

Details:

On HS-FS device ROM applies debug restrictions to FWL 33 and 66 which contains secure assets. The debug access restriction was applied to the entire firewall region and not just to the region which applies to the secure asset. This prevent the use of an external emulator to be able to perform initial flash programming for example without requiring TIFS SW to in the picture.

Workaround(s):

TIFS SW is needed to be able to request the needed firewall to be open.
