Subject: [ 092/108] ACPI: Remove one board specific WARN when ignoring timer overriding

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Feng Tang <feng.tang@...el.com>

commit 5752cdb805ff89942d99d12118e2844e7db34df8 upstream.

commit 7f68b4c2e158019c2ec494b5cfbd9c83b4e5b253 upstream.

Current WARN msg is only for the ati_ixp4x0 board, while this function
is used by mulitple platforms. So this one board specific warning
is not appropriate any more.
