msm: ipa: pipe reallocation 



Reallocated endpoint numbers according to a predefined list. This enables
Modem processor to use IPA HW in addition to Apps processor. As a part of
this change, the following changes were made:
- Add new clients for IPA 2.0
- Reallocate endpoint numbers to the new and existing pipes
- Removed usage of IPA mode parameter
- Changed the initialization of ep_mapping array so it is more
manageable
