Subject: [PATCH 1/3] mmc: renesas_sdhi: Deassert the reset signal on probe

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Deassert the reset signal of the SDHI controller during probe to avoid
relying on the previous bootloaders. Without deasserting the reset signal,
the SDHI controller will not function.
