Subject: libre: uboot4extlinux-am335x: fix filesystem corruption

Before that u-boot.img was to be located at 384k on the microSD,
as CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR defaults to 0x300.

CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR states:
  Address on the MMC to load U-Boot from, when the MMC is being used
  in raw mode. Units: MMC sectors (1 sector = 512 bytes).

However since once built, u-boot.img size was 692k, it went over
the 1MB empty space that is usually created when parititoning
block devices, effectively corrupting the first partition.
