The patch extends card_detect and write_protect support to get mx5
family and more scenarios supported.  The changes include:

 * Turn platform_data from optional to mandatory
 * Add cd_types and wp_types into platform_data to cover more use
   cases
 * Remove the use of flag ESDHC_FLAG_GPIO_FOR_CD
 * Adjust some machine codes to adopt the platform_data changes
 * Work around the issue that software reset will get card detection
   circuit stop working

With this patch, card_detect and write_protect gets supported on
mx5 based platforms.

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.

 * Add a list to save all mx2 ports references, so that
   mx2_gpio_irq_handler can walk through all interrupt status
   registers

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxc_gpio_init into mxc_gpio_probe function

 * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
   be public at all, and also make some other cleanup on
   plat-mxc/include/mach/gpio.h at the same time

And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

<mach/devices-common.h>.  The latter already includes many headers
that the machine files don't need to include again.

These were found by:

Current code inside babbage_usbhub_reset uses gpio_direction_output with initial value of the GPIO and also sets

By using gpio_request_one it is possible to set the direction and initial value in one shot.

This patch actually replaces the 'struct pad_desc' with a u64 cookie
to facilitate adding platform specific pad_ctrl settings to an
existing pad definition.

So, instead of:
	iomux_v3_cfg_t power_key = MX51_PAD_EIM_A27__GPIO_2_21;
	power_key.pad_ctrl = MX51_GPIO_PAD_CTRL_2;
	mxc_iomux_v3_setup_pad(&power_key);
one can write:
	mxc_iomux_v3_setup_pad((MX51_PAD_EIM_A27__GPIO_2_21 & ~MUX_PAD_CTRL_MASK) | MX51_GPIO_PAD_CTRL_2);

Currently, to define a GPIO number, we're using something like :

#define EFIKAMX_PCBID0         (2*32 + 16)

to define GPIO 3 16.

This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :

#define EFIKAMX_PCBID0         IMX_GPIO_NR(3, 16)

v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR
