The SDCLK is divided down from the host controller clock. Host
controller clock may be different from the maximum SDCLK, so
get it from the platform, instead of just using the max SDCLK.

Patch "mmc: sdhci: Add size for caller in init+register" changed the
interface for sdhci_pltfm_init, while patch "mmc: sdhci-sirf: add mmc
host sdhci-pltfm based driver for SiRF SoCs" added a new driver
with the old interface.
This changes the sirf driver to use the new interface, avoiding
one warning, and simplifying the init sequence. Since we're here
already, this also adds an error path for failed clk_prepare_enable.

With MMC clock gating enabled the MMC core currently calls MMC host driver's
.set_ios() method with .power_mode == MMC_POWER_ON and the clock value set
either to 0 or to the target rate. The tmio MMC driver then wrongly
translates the latter calls to card slot power-on requests, even when the
slot already was on. This patch fixes the driver to avoid needlessly
incrementing power-supplying regulator's use count.

Masking events on MMCIF means that an occurrence of the masked event
won't raise an interrupt, but the event bit will still be set in the
interrupt status register. If simultaneously a different event occurs
which was enabled, both flags will be set. However, only the unmasked
event bit should be cleared in the status register in such a case.
Clearing also the masked bit can lead to lost interrupts, which indeed
can be observed on the armadillo800eva r8a7740 board with an eMMC chip.
The problem has been introduced by the recent "mmc: sh_mmcif: simplify
IRQ processing" patch. Fix the problem by only clearing enabled interrupts.

When resuming, the tmio_mmc_host_resume() function is run when the
controller might still be powered down. Issuing a reset command to it at
that time has no effect. This patch postpones resetting the controller

So far only the SDHI implementation uses TMIO MMC with DMA. That way a DMA
channel filter function, defined in the TMIO driver wasn't a problem.
However, such a filter function is DMA controller specific. Since the SDHI
glue is only running on systems with the SHDMA DMA controller, the filter
function can safely be provided by it. Move it into SDHI.

The eSDHC controller on the i.MX53 needs an additional, non spec
compliant CMD12 after a multiblock read with a predefined number of
blocks. Otherwise the internal state machine won't go back to the
idle state.
This commit effectively reverts 5b6b0ad6 (mmc: sdhci-esdhc-imx:
fix for mmc cards on i.MX5), which fixed part of the problem by
making multiblock reads work, however this fix was not sufficient
when multi- and singleblock reads got intermixed.
This implements the recommended workaround (Freescale i.MX Reference
Manual, section 29.6.8 "Multi-block Read") by manually sending a
CMD12 with the RSPTYP bits cleared.

Currently SDIO interrupts do not work on i.MX53 and maybe others.
This was observed with a Marvell 8787 based SDIO wifi adapter
using the mwifiex driver and firmware from the Marvell git
repository.
The symptom was a timeout after firmware download.
Observing the SDIO_DAT1 line showed that an interrupt was requested
(level 0) but no interrupt was generated in software, the line
stayed low until a timeout ocurred and the card was reset.
There is a Freescale errata
ENGcm11186 "eSDHC misses SDIO interrupt when CINT is disabled"
The workaround suggested by this errata is already implemented and
involves clearing and then setting the D3CD bit in the host control
register [see esdhc_writel_le()]
However, when esdhc_writeb_le() is later used to write to
SDHCI_HOST_CONTROL it always resets the D3CD bit.
To fix this simply add the D3CD bit to the set of bits
not modified by esdhc_writeb_le().
