Subject: [PATCH] omap2/3/4: serial: Half revert multiboot changes

The patch named:
  "omap2/3/4: Fix mach-omap2/serial.c for multiboot"

Which added UART4 init also for 36xx based boards, broke zoom3
booting. External UART must be correctly initialized already
by board-zoom-debugboard.c file, therefore the addition on UART4
initialization can't be done blindly (i.e. board agnostic)

This patch removes the 36xx uart4 init for the above reason.
