[U-Boot] [PATCH 1/1] mmc: stm32_sdmmc2: increase polling status register delay

[patrice.chotard at st.com]

From: Christophe Kerello <christophe.kerello at st.com>

MMC commands like MMC_CMD_ALL_SEND_CID or MMC_CMD_SEND_CSD can reach
500 us. This patch increases the polling status register delay to avoid
a timeout on a command.
