omap3_beagle: Flush UART3 xmit on enable if TEMT is broken
Flush UART3 xmit on enable if TEMT is broken On some OMAP3 devices when UART3 is configured for boot mode before SPL starts only THRE bit is set. We have to empty the transmitter before initialization starts. This patch avoids the use of CONFIG_SYS_NS16550_BROKEN_TEMT.
