Introduce SDIO runtime PM support: 1. Power to SDIO cards is kept low until one of its functions is bound (i.e. a matching driver is successfully probed) 2. If the matching driver supports runtime PM, power to the card is dropped soon after probe() returns.

The systems typically come with sdhci-acpi driver used for the SDIO host controller, which does runtime-pm. However, the brcmfmac driver does not support runtime-pm so when host controller goes into runtime suspend the firmware can not communicate with the host and brcmfmac is idle as it waits for firmware response.

While this obviously means that we could save some power there, it also creates issues when it comes to EMC control since we'll have a perfect peak at the card clock rate. Let's implement runtime_pm with autosuspend so that we will shut down the controller when it's not been in use for quite some time.

Using compat-wireless the wl12xx driver and its dependencies can be compiled for kernels >= 2.6.30. Note: For very old kernels you may also need a few patches to your kernel. Here follows a few hints for old kernels. Kernel 2.6.36 and older. SDIO runtime PM support - here. Lenient generic runtime pm callbacks - here. Add platform data passing ...

To that end, we'll disable runtime_pm when we detect that an SDIO card was inserted. This is much like with what we do with the special "SDMMC_CLKEN_LOW_PWR" bit that dw_mmc supports. NOTE: we specifically do this Runtime PM disabling at card init time rather than in the enable_sdio_irq() callback. This is _different_ than how SDHCI does it.
