[ekohl] 47765: [VFATLIB] - Get rid of the hard-coded sector size as large sector (4KB) harddisks are already available. - When a partition is formatted, choose the FAT type according to the partition type. The size of the partition does not matter here as it is up to the caller to set the right partition type according to its size.

[VFATLIB]
- Get rid of the hard-coded sector size as large sector (4KB) harddisks are already
available.
- When a partition is formatted, choose the FAT type according to the partition type. The
size of the partition does not matter here as it is up to the caller to set the right
partition type according to its size.
