Yu Zhao 8c2c6a9aa9 mmc: sdhci-pci-o2micro: Add quirk for O2 Micro dev 0x8620 rev 0x01 
[ Upstream commit 5169894982 ]

This device reports SDHCI_CLOCK_INT_STABLE even though it's not
ready to take SDHCI_CLOCK_CARD_EN. The symptom is that reading
SDHCI_CLOCK_CONTROL after enabling the clock shows absence of the
bit from the register (e.g. expecting 0x0000fa07 = 0x0000fa03 |
SDHCI_CLOCK_CARD_EN but only observed the first operand).

mmc1: Timeout waiting for hardware cmd interrupt.

mmc1: sdhci: ============================================

The problem happens during wakeup from S3. Adding a delay quirk
after power up reliably fixes the problem.
