[ Upstream commit 3c482e1e830d79b9be8afb900a965135c01f7893 ]
The driver overrides the error codes returned by platform_get_irq() to
-EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.

For commands that doesn't involve to prepare a data transfer, owl-mmc is
using a fixed 30s response timeout. This is a bit problematic.
For some commands it means waiting longer than needed for the completion to
expire, which may not a big issue, but still. For other commands, like for
an erase (CMD38) that uses a R1B response, may require longer timeouts than
30s. In these cases, we may end up treating the command as it failed, while
it just needed some more time to complete successfully.
Fix the problem by respecting the cmd->busy_timeout, which is provided by
the mmc core.

Add SD/MMC driver for Actions Semi Owl SoCs. This driver currently
supports standard, high speed, SDR12, SDR25 and SDR50. DDR50 mode is
supported but it is untested. There is no SDIO support for now.
