[PATCH v4 2/2] mmc: sdhci_am654: Add SDHCI_QUIRK2_SUPPRESS_V1P8_ENA quirk to am62 compatible

[Judith Mendez <jm@ti.com>]

Add a new struct for platform data for the ti,am62-sdhci compatible to
apply additional quirks, namely "SDHCI_QUIRK2_SUPPRESS_V1P8_ENA", to
host controllers with am62 compatible.

This fixes MMC init failures seen across am62x boards.

Fixes: ac5a41b472b4 ("Revert "mmc: sdhci_am654: Add sdhci_am654_start_signal_voltage_switch"")
Fixes: 941a7abd4666 ("mmc: sdhci_am654: Add sdhci_am654_start_signal_voltage_switch")
