If the ACPI flag "non-removable" is present and true for an SD/MMC
slot, then set a new flag on that slot to indicate that the media
is non-removable. Make sdhc_card_detect always return true for a
slot if its non-removable media flag is set.

This change lets the kernel automatically configure the
permanently-installed MMC slot on the NXP LX2160-based HoneyComb
LX2 board.

sdhc: Retire SDHC_FLAG_USE_ADMA2 flag.

ADMA2 support in sdhc is mature now, so no need for it to be opt-in.

32-bit build fix

acpi: sdhc: Read caps2 even if sdhci-caps{,-mask} doesn't touch the bits

SDHC_FLAG_HOSTCAPS means that the driver has to supply both caps and caps2
values.

acpi: sdhc: Add support for RK356x eMMC controller.

RK356x has a DesignWare eMMC controller that is somewhat SDHCI compliant,
with one major problem -- the clock divisor doesn't actually work. To
change the clock card on Rockchip SoCs, the clock frequency needs to be
adjusted in the Clock & Reset Unit (CRU) directly.

The RK356x UEFI implementation introduces a DSM that allows drivers to
request firmware assistance in setting the card clock rate, for instances
like this where the divisor is broken.

From the UEFI README:

Function 1: Set Card Clock

The _DSM control method parameters for the Set Card Clock function are
as follows:

Arguments

* Arg0: UUID = 434addb0-8ff3-49d5-a724-95844b79ad1f
* Arg1: Revision = 0
* Arg2: Function Index = 1
* Arg3: Target card clock rate in Hz.

Return

The actual card clock rate in Hz. Will be less than or equal to the
target clock rate. Returns 0 if the target clock rate could not be set.

acpi: sdhc: Support sdhci-caps and sdhci-caps-mask properties.

acpi: sdhc: Ignore clkbase register if clock-frequency property is present

fix build

use designated initializers

Use acpi_match_hid to match both _HID and _CID

branches: 1.9.2;
Read clock frequency from device properties

convert more KM_NOSLEEP to KM_SLEEP and remove code to handle failures.

Attempt to appease gcc and unbreak i386 build. Should be NFC.

Use acpi_md_intr_establish/disestablish to handle device IRQs. The existing
code abused AcpiOsInstallInterruptHandler, which is meant for installing
the SCI handler.
