disk: part_dos: Align dos_partition_t with struct partition
The dos_partition_t struct defined in part_dos.h is nearly identical to
the struct partition defined in part_efi.h. They differ primarily in how
define their starting sector and number of sectors fields.
The former uses unsigned char arrays while the latter uses __le32 types.
Using __le32 is preferable, as it removes the ambiguity and potential
misuse of a raw byte array. This also aligns the structure with how the
Linux kernel defines it nowadays, which is the original source of it.
To prepare for future consolidation where one of the data structures can
be removed, this change aligns both definitions and updates all accessors
for dos_partition_t.
