mmc: increase MMC SDHCI read status timeout
Otherwise, ocassionally see errors like this:
Flashing sparse image at offset 2078720
Flashing Sparse Image
sdhci_send_command: Timeout for status update!
mmc fail to send stop cmd
write_sparse_image: Write failed, block #2181088 [0]
This does not affect the actual writing speed, which is controlled by
the default value:
CONFIG_SDHCI_CMD_DEFAULT_TIMEOUT
It only increases the retries when reading:
SDHCI_INT_STATUS
to avoid the timeout error.
