mmc: core: Allows to override the timeout value for ioctl() path
Occasionally, user-land applications initiate longer timeout values for certain commands
through ioctl() system call. But so far we are still using a fixed timeout of 10 seconds
in mmc_poll_for_busy() on the ioctl() path, even if a custom timeout is specified in the
userspace application. This patch allows custom timeout values to override this default
timeout values on the ioctl path.
