The commit id "5550bc33a1a9002976022cc794fe8c52ad9a0021" seems to be broken
zoom3 boot which adds support for UART4 on OMAP4 and OMAP3630.
But, it looks like OMAP3630 UART4 interface and functional clock nodes needs
to be added for omap3630. Thus limiting no. of UART's for 3630 to 3 to prevent
boot up issues until clock nodes are added for UART4 on OMAP3630.
