mmc: sdhci-of-esdhc: add/remove some quirks according to vendor version

Browse source

A previous patch had removed esdhc_of_platform_init() by mistake.
static void esdhc_of_platform_init(struct sdhci_host *host)
{
	u32 vvn;

	vvn = in_be32(host->ioaddr + SDHCI_SLOT_INT_STATUS);
	vvn = (vvn & SDHCI_VENDOR_VER_MASK) >> SDHCI_VENDOR_VER_SHIFT;
	if (vvn == VENDOR_V_22)
		host->quirks2 |= SDHCI_QUIRK2_HOST_NO_CMD23;

	if (vvn > VENDOR_V_22)
		host->quirks &= ~SDHCI_QUIRK_NO_BUSY_IRQ;
}

This patch is used to fix it by add/remove some quirks according to
verdor version in probe.
