net: ipa: define IPA_MEM_END_MARKER
Define a new pseudo memory region identifer that specifies the
offset at the end of IPA resident memory. Use it instead of
IPA_MEM_UC_EVENT_RING in places where the size of that region was
defined to be 0.
The size of the IPA_MEM_END_MARKER pseudo region must be zero.
