Root cause was found and truns out only one patch could fix this issue,
reopen then.

** Description changed:

- Intel Braswell eMMC need some backports:
+ This patch could fix this issue, otherwise booting will take a very long

- mmc: sdhci-acpi: Get UID directly from acpi_device
- mmc: sdhci-acpi: Pass HID and UID to probe_slot
- mmc: sdhci-acpi: Fix Braswell eMMC timeout clock frequency
- mmc: sdhci-acpi: add probe_slot method for emmc/sd/sdio
- mmc: card: Prevent partition scan for the eMMC boot areas
- mmc: sdhci-pci: Fix Braswell eMMC timeout clock frequency
- mmc: sdhci: Add PCI IDs for Intel Braswell
- mmc: sdhci: Let a driver override timeout clock frequency(have some conflicts)
