Tegra186's MMC controller needs to be explicitly identified. Add another
compatible value for it.
Tegra186 will use an entirely different clock/reset control mechanism to
existing chips, and will use standard clock/reset APIs rather than the
existing Tegra-specific custom APIs. The driver support for that isn't
ready yet, so simply disable all clock/reset usage if compiling for
Tegra186. This must happen at compile time rather than run-time since the
custom APIs won't even be compiled in on Tegra186. In the long term, the
plan would be to convert the existing custom APIs to standard APIs and get
rid of the ifdefs completely.
The system's main eMMC will work without any clock/reset support, since
the firmware will have already initialized the controller in order to
load U-Boot. Hence the driver is useful even in this apparently crippled
state.

Add support for enabling CONFIG_BLK with MMC. This involves changing a
few functions to use struct udevice and adding a MMC block device driver.
Signed-off-by: Simon Glass <sjg@chromium.org>
Binding an MMC device when CONFIG_BLK is enabled requires that a block
device be bound as a child of the MMC device. Add a function to do this.
The mmc_create() method will be used only when DM_BLK is disabled.
Add an unbind method also.

At present the MMC subsystem maintains its own list of MMC devices. This

omap_hsmmc driver directly typecasts fdt_addr_t to a pointer.
This is not strictly correct, as it gives a build warning when
fdt_addr_t is u64. So, use map_physmem for a proper typecasts.
This is inspired by commit 167efe01bc ("dm: ns16550: Use an address

Support Driver Model for fsl esdhc driver.
1. Introduce a new structure struct fsl_esdhc_priv
2. Refactor fsl_esdhc_initialize which is originally used by board code.
- Introduce fsl_esdhc_init to be common usage for DM and non-DM
- Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part.
- The original API for board code is still there, but we use
'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it.
3. All the functions are changed to use 'struct fsl_esdhc_priv', except
fsl_esdhc_initialize.
4. Since clk driver is not implemented, use mxc_get_clock to geth
the clk and fill 'priv->sdhc_clk'.

When enable dcache on HiKey, we're running into MMC command timeouts
because our retry loop is now faster than the eMMC (or an external SD
card) can answer.
Increase the retry count to the same as the timeout value for status
reports.
The real fix is obviously to not base this whole thing on a cycle counter
but on real wall time, but that would be slightly more intrusive.

Boards using the TWL6030 regulator may not all use the LDOs the same way.
Some might also not use MMC1 at all, so VMMC would't have to be enabled.
This delegates TWL6030 MMC power initializations to board-specific functions,
that may still call twl6030_power_mmc_init for the default behavior.
