    mmc: sdhci: fix two compile errors

    | CC drivers/mmc/host/sdhci.o
    | drivers/mmc/host/sdhci.c: In function 'sdhci_execute_tuning':
    | drivers/mmc/host/sdhci.c:1990:4: error: implicit
    | declaration of function 'sdhci_do_reset'
    | [-Werror=implicit-function-declaration]
    | sdhci_do_reset(host, SDHCI_RESET_CMD);
    | ^
    | drivers/mmc/host/sdhci.c:2006:7: error: 'struct
    | mmc_command' has no member named 'busy_timeout'
    | cmd.busy_timeout = 50;
    |        ^

    In function sdhci_execute_tuning, replace sdhci_do_reset
    with sdhci_reset, replace busy_timeout with cmd_timeout_ms.

    Commit a629a90ba0 adds eMMC DDR mode support for t2080qds and
    modified some data structures and function name. Later
    commit a2080cc280 just backport upstream commit 61e53bd004
    without aligning the current source tree thus cause
    these build errors. Fix them.
