mmc: sirf: fix sdhci_pltfm_init sequence

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.

mmc: core: Support aggressive power management for (e)MMC/SD

Aggressive power management is suitable when saving power is
essential. At request inactivity timeout, aka pm runtime
autosuspend timeout, the card will be suspended.

Once a new request arrives, the card will be re-initalized and
thus the first request will suffer from a latency. This latency
is card-specific, experiments has shown in general that SD-cards
has quite poor initialization time, around 300ms-1100ms. eMMC is
not surprisingly far better but still a couple of hundreds of ms
has been observed.

Except for the request latency, it is important to know that
suspending the card will also prevent the card from executing
internal house-keeping operations in idle mode. This could mean
degradation in performance.

To use this feature make sure the request inactivity timeout is
chosen carefully. This has not been done as a part of this patch.

Enable this feature by using host cap MMC_CAP_AGGRESSIVE_PM and
by setting CONFIG_MMC_UNSAFE_RESUME.

mmc: block: Enable runtime pm for mmc blkdevice

Once the mmc blkdevice is being probed, runtime pm will be enabled.
By using runtime autosuspend, the power save operations can be done
when request inactivity occurs for a certain time. Right now the
selected timeout value is set to 3 s. Obviously this value will likely
need to be configurable somehow since it needs to be trimmed depending
on the power save algorithm.

For SD-combo cards, we are still leaving the enablement of runtime PM
to the SDIO init sequence since it depends on the capabilities of the
SDIO func driver.

Moreover, when the blk device is being suspended, we make sure the device
will be runtime resumed. The reason for doing this is that we want the
host suspend sequence to be unaware of any runtime power save operations
done for the card in this phase. Thus it can just handle the suspend as
the card is fully powered from a runtime perspective.

Finally, this patch prepares to make it possible to move BKOPS handling
into the runtime callbacks for the mmc bus_ops. Thus IDLE BKOPS can be
accomplished.

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.

However, when esdhc_writeb_le() is later used to write to

Pull devm usage cleanup from Wolfram Sang:
 "Lately, I have been experimenting how to improve the devm interface to
  make writing device drivers easier and less error prone while also
  getting rid of its subtle issues.  I think it has more potential but
  still needs work and definately conistency, especiall in its usage.

  The first thing I come up with is a low hanging fruit regarding
  devm_ioremap_resouce().  This function already checks if the passed
  resource is valid and gives an error message if not.  So, we can
  remove similar checks from the drivers and get rid of a bit of code
  and a number of inconsistent error strings.

  This series only removes the unneeded check iff devm_ioremap_resource
  follows platform_get_resource directly.  The previous version tried to
  shuffle code if needed, too, what lead to an embarrasing bug.  It
  turned out to me that shuffling code for all cases found will make the
  automated script too complex, so I am unsure if an automated cleanup
  is the proper tool for this case.  Removing the easy stuff seems
  worthwhile to me, though.

  Despite various architectures and platform dependencies, I managed to
  compile test 45 out of 57 modified files locally using heuristics and
