mmc: renesas_sdhi: Get the reset handle early in the probe

[ Upstream commit 2f351880bf7d878480da4278e0ded4982dff5cea ]

In case of devm_reset_control_get_optional_exclusive() failure we returned
directly instead of jumping to the error path to roll back initialization.

This patch moves devm_reset_control_get_optional_exclusive() early in the
probe so that we have the reset handle prior to initialization of the
hardware.
