Subject: [PATCH 5.2 097/143] mmc: sdhci-sprd: add SDHCI_QUIRK2_PRESET_VALUE_BROKEN

From: Chunyan Zhang <chunyan.zhang@...soc.com>

commit 6a526f66ab1494b63c71cd6639d9d96fd7216add upstream.

The bit of PRESET_VAL_ENABLE in HOST_CONTROL2 register is reserved on
sprd's sd host controller, set quirk2 to disable configuring this.

Fixes: fb8bd90f83c4 ("mmc: sdhci-sprd: Add Spreadtrum's initial host controller")
