[MA35D1] Adding Partitions with eMMC/SD Card

Application	This sample code introduces the method of adding primary partitions, extended partitions, and logical partitions on the SD card/eMMC on the MA35D1 Buildroot platform.
BSP Version	Buildroot_2024
Hardware	NuMaker-HMI-MA35D1-S1 V1.0

The current software of MA35D1's SD card and eMMC does not support GPT (GUID Partition Table) partition booting and only uses MBR (Master Boot Record) partition mode. This partition mode supports up to 4 primary partitions. If more partitions are needed, an extended partition should be created outside the primary partitions, and then multiple logical partitions can be created on this extended partition, thus breaking through the 4-partition limitation of MBR.
