device/resource_allocator_v4: Only highlight log message with ===

Currently, four instead of three = are used in one log message.

    Done reading resources.
    ==== Resource allocator: DOMAIN: 0000 - Pass 1 (gathering requirements) ===
    === Resource allocator: DOMAIN: 0000 - Pass 2 (allocating resources) ===

As the ending mark is `===` change it to `===` in the beginning.

    Done reading resources.
    === Resource allocator: DOMAIN: 0000 - Pass 1 (gathering requirements) ===
    === Resource allocator: DOMAIN: 0000 - Pass 2 (allocating resources) ===
