OMAP3: igep00x0: add CONFIG_SYS_NS16550_BROKEN_TEMT

IGEP board PC16550D (ns16550) UART doesn't set the Transmitter Empty (TEMT) Bit in SPL. This makes U-Boot to hang while waiting for TEMT. Add the CONFIG_SYS_NS16550_BROKEN_TEMT config option to avoid this issue. Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk>
