ARM: OMAP2+: UART: Avoid console uart idling during bootup
Omap-uart can be used as console uart to print early boot messages using earlyprintk so for console uart prevent hwmod reset or idling during bootup. Identify omap-uart used as console and avoid idling rather than preventing all omap-uarts from idling during bootup. Update the comments for the same. Remove the uart idling and enabling back using hwmod_idle/omap_device_enable for all uarts that where left enabled from boot to set the hwmod framework state machine right. This need not be taken care any more serial.c rather can be handled within the hwmod framework.
