da850evm: Move LPSC configuration to board_early_init_f()
Since commit f1d2b313c9eb6808d30c16a9eb5251240452a56c the serial port of the da850evm is accessed before the UART2 peripheral of the SoC is powered on in the function board_init() in board/davinci/da8xxevm/da850evm.c. When u-boot is used in conjunction with the UBL (user boot loader, see doc/README.davinci) on this board, the UART2 peripheral is already turned on by UBL at the time u-boot is started. Hence, the wrong initialization sequence is not noticed by most users. However, if UBL is not used, u-boot must power on the peripheral before using it. This patch adds a board_early_init_f() function for the LPSC configuration to the da850evm board configuration.
