The IPA filter/routing hash enable register and filter/routing hash
flush register each have four single-bit fields representing the
four hashed tables to be enabled or flushed. The field positions
are identical, so just use a single set of field masks to represent
the fields for both registers.

Looks like u32p_replace_bits() should be used instead of
u32_replace_bits() which does not modifies the value but returns the
modified version.

This commit affects comments (and in one case, whitespace) only.
Throughout the IPA code, return statements are documented using
"@Return:", whereas they should use "Return:" instead. Fix these
mistakes.
In function definitions, some parameters are missing their comment
to describe them. And in structure definitions, some fields are
missing their comment to describe them. Add these missing
descriptions.
Some arguments changed name and type along the way, but their
descriptions were not updated (an endpoint pointer is now used in
many places that previously used an endpoint ID). Fix these
incorrect parameter descriptions.
In the description for the ipa_clock structure, one field had a
semicolon instead of a colon in its description. Fix this.
Add a missing function description for ipa_gsi_endpoint_data_empty().
All of these issues were identified when building with "W=1".

This patch contains code implementing filter and routing tables for
the IPA. A filter table allows rules to be used for filtering
packets that depart the AP at an endpoint. A filter table entry
contains the address of a set of rules to apply for each endpoint
that supports filtering.
A routing table allows packets to be routed to an endpoint based
on packet metadata. It is also a table whose entries each contain
the address of a set of routing rules to apply.
Neither filtering nor routing is supported by the current driver.
All table entries refer to rules that mean "no filtering" and "no
routing."
