omap: rx51: Set regulator V28_A always on



The V28_A domain in Nokia N900 that supplies VDD voltages to TLV320AIC34 and
TPA6130A2 should not be shutdown. This is because otherwise there will be
leak from VIO to VDD in TLV320AIC34 and this leak consumes more battery
current that is saved from keeping V28_A off. With this patch the battery
current consumption is approximately 1.5 mA lower.

Thanks to Kalle Jokiniemi <kalle.jokiniemi@nokia.com> for noticing the issue.
