rpi3: sdhost: SDHost driver improvement
This commit improves the SDHost driver for RPi3 as following: * Unblock MMC_CMD(17). Using MMC_CMD(17) is more efficient on block reading. * In some low probability that SEND_OP_COND might results CRC7 error. We can consider that the command runs correctly. We don't need to retry this command so removing the code for retry. * Using MMC_BUS_WIDTH_1 as MMC default value to improve the stability. * Increase the clock to 50Mhz in data mode to speed up the io. * Change the pull resistors configuration to gain more stability.
