In these experiments I actually gated not only the
SET_BLOCK_COUNT CMD23 is needed for all access to RPMB partition.
If block count is not set by CMD23, all subsequent read/write commands
fail as per eMMC specification. So, If the host does not support CMD23,
do not expose RPMB partition.
Accessing RPMB partition can cause hang / huge delay

through register or callback function is useless. So skip current
redundant code.
2. If SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK is selected, host uses
SDCLK instead of TMCLK for data timeouts. So host-timeout_clk

If sdio host can wakeup system, interrupts will _NOT_ be disabled
and sdio card interrupt may happen during whole suspend/resume process.
Then the card interrupts received after suspend while before resume
back should be regard as wakeup event. So set a wakeup event at
that point. All sdio
