Detailed Description

Defines the HAL interface for lower layer to support SD/MMC library.

Usage

1. Implement HAL functions as and sSdHalFunctions instance.
2. Invoke SDD_Initialize() to initialize sSdCard instance with implemented HAL functions.
   1. The default SD/MMC bus HAL initialize function name is SDD_InitializeSdmmcMode(), which invokes SDD_Initialize()
   2. The default SPI bus HAL initialize function name is SDD_InitializeSpiMode(), which invokes SDD_Initialize()
