/*
 * This function initializes the SDIO driver.
 *
 * The following initializations steps are followed -
 *      - Read the Host interrupt status register to acknowledge
 *        the first interrupt got from bootloader
 *      - Disable host interrupt mask register
 *      - Get SDIO port
 *      - Initialize SDIO variables in card
 *      - Allocate MP registers
 *      - Allocate MPA Tx and Rx buffers
