qcacmn: Add qdf_ptr_hash
While the Linux kernel provides a generic hash table data structure, it
makes the assumption that it will always be referred to statically, so
as to avoid having to store the size of the hash table's internal array.
This limitation means reusing this data type generically is difficult or
impossible.
Add a very simple hash table implementation to WLAN for general use,
which stores its own size information, and assumes all input keys will
be pointers. Build on top of the recently added single-linked list
implementation added in I2959f34649a0d8e0b312d9d67c81de17753b9b6c to
reduce memory overhead.
