or it will cause null-ptr-deref, because of deleting a not added

If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().

To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().

In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.

Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

SDHCI_QUIRK_MISSING_CAPS is not needed because __sdhci_read_caps() can be
called instead.

In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace
SDHCI_QUIRK_MISSING_CAPS with __sdhci_read_caps() for Ricoh SDHCI
controller.

__sdhci_read_caps() is also called from sdhci_setup_host() via
sdhci_read_caps(), however only the first call to __sdhci_read_caps() does
anything because after that host->read_caps has been set to true.

Note, __sdhci_read_caps() does more than just set host->caps, such as do a
reset, so calling __sdhci_read_caps() earlier could have unforeseen
side-effects. However the code flow has been reviewed with that in mind.
