MFC r292419, r294237:

Fix the clock divisor calc for imx6 sdcard bus speed.

Quick exit after setting the clock control register.

MFC: r270885, r270948

- Nuke unused sdhci_softc.
- Static'ize sdhci_debug local to sdhci.c.
- Const'ify PCI device description strings.
- Nuke redundant resource ID members from sdhci_pci_softc.
- Nuke unused hw.sdhci_pci.debug tunable.
- Add support for using MSI instead of INTx, controllable via the tunable
hw.sdhci.enable_msi (defaulting to on) and tested with a RICOH R5CE823 SD
controller.
- Use NULL instead of 0 for pointers.

MFC 264977:

Stop calling imx51_ccm_foo() clock functions from imx6 code. Instead
define a few imx_ccm_foo() functions that are implemented by the imx51
or imx6 ccm code.

MFC 264052, 264057, 264065, 264094, 264103, 264120

Actually save the mpcore clock frequency retrieved from fdt data.

imx6..
- Don't call sdhci_init_slot() until after handling the FDT properties
related to detecting card presence.
- Flag several sysctl variables as tunables.
- Rework the cpu frequency management code for imx6 to add "operating
points" and min/max frequency controls.

generic timer...
- Setup both secure and non-secure timer IRQs.
We don't know our ARM security state, so one of them will operate.
- Don't set frequency, since it's unpossible in non-secure state.
Only rely on DTS clock-frequency value or get clock from timer.

Add a driver to provide access to imx6 on-chip one-time-programmble data.

Make it possible to access the ocotp registers before the ocotp device
is attached, by establishing a temporary mapping of the registers when
necessary.

It turns out Freescale cleverly made the ocotp device compatible across
several different families of SoCs, so move it to the freescale directory
and prefix everything with fsl rather than imx6.

Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler
to a callout.

Increase the wait time for acquiring the SD bus from 10 to 250ms.

If no compatible cards were found after probing the SD bus, say so.

Add timeout logic to sdhci, separate from the timeouts done by the hardware.

After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA
rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing
any possibility of recovering from the error.

Add a helper routine to depth-search the device tree for a node with a
matching 'compatible' property.

On armv6 and later, use the WriteNotRead bit of the fault status register
to decide what protections are required by the faulting access.

Use the right symbols for determining arm architecture. Include the
necessary header file which has the new FAULT_WNR symbol defined in it.

Allow the kernel to be loaded at any 1MiB address. This requirement is
because we use the 1MiB section maps as they only need a single pagetable.

Add function for configuring Vybrid PLL4 (Audio) clock frequency output.

imx6 changes ...

- Fix the definition of the SDHCI_STATE_DAT and SDHCI_STATE_CMD fields,
and add SDHCI_RETUNE_REQUEST. None of these are actually used in the
code yet.

- Write translation code for the SDHCI_PRESENT_STATE register.
Freescale moved some bits around in their version of the register,
adjust things so that the sdhci code sees the standard layout.

- Add standard non-removable and cd-gpios properties to the usdhc
devices. That generates references to gpio devices, so uncomment them
even though there isn't a gpio driver to do anything with them yet.

- Add handling of standard "non-removable" property, and also some
workaround code so that if card detect is wired to a gpio pin, for now
we just treat it the same as non-removable (because there isn't a gpio
driver yet).

- Enable both sdcard slots, but not the sdio-based wifi that we don't
yet have a driver for.

- Remove a couple obsolete function declarations.

MFC r261410

Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

MFC r257561:

Bugfix: the attach routine needs to use the same table of fdt compat
strings that the probe routine used.

MFC r257454: Add sdhci driver glue for imx family SoCs.

Add sdhci driver glue for imx family SoCs. This should support both uSDHC
(newer SoCs) and eSDHC (older SoCs), but the eSDHC support is untested and
likely to need some tweaking.
