[ARM] pxa/vpac270: add ide support

Browse Source 
This patch adds support for the on-board IDE channel. I tested this with a CDROM
connected over 2.5-3.5 IDE reduction with external power supplied to the CDROM.
This was not tested with the Voipac 270-HDD-000 (official Voipac HDD module),
but I expect no problems.
