[PATCH 03/11] OMAP: hwmod: Fix omap_hwmod_reset wrong state test

From: Liam Girdwood <lrg at slimlogic.co.uk>
The reset function wrongly used the state flag as a bit mask and was trying
to re-enable after a reset.
hwmod is still enabled for the PRCM point of view after a softreset
so there is no need to re-enable.
Remove the state check from omap_hwmod_reset since the _reset
function is checking that as well and in addition can generate
a warning
