meta-yocto-bsp: beaglebone: Set a fixed size for boot partition in WIC image
After the dosfstools has been updated to v4.2 by commit b522f24723e1 ("dosfstools: update 4.1 -> 4.2"), the commit b29eb5be67e9 ("mkfs.fat: Align total number of sectors to be multiple of sectors per track") in v4.2 has caused a regression in beagebone black board. The reason is that the real total sectors of the fat filesystem created by the mkdosfs may not be the same size as what we requested due to align with the sectors per track, this change seem no side effect to linux kernel, but it breaks the beaglebone black boot ROM and make it can't load the MLO. In order to fix this issue, we choose to set a fixed size for the boot partition to make sure that the total sectors always are aligned with the sectors per track.
