[PATCH 2/2] arm64: dts: ti: k3-am64: Set MMC1_CLK pin as OUTPUT

[Sai Sree Kartheek Adivi]

From: Judith Mendez <jm at ti.com>

MMC clock pins must be configured as OUTPUT-only per TRM specification [0]
with receiver disabled (RXACTIVE bit = 0). Change MMC1_CLK from PIN_INPUT
to PIN_OUTPUT in AM64 device trees to match documentation.
