3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tony Prisk <li...@prisktech.co.nz>
commit 532db570e5181abc8f4f7bfa6c77c69ec2240198 upstream.
Control register bitfield for 12H/24H mode is handled incorrectly.
Setting CR_24H actually enables 12H mode. This patch renames the define
and changes the initialization code to correctly set 24H mode.
