Add support for Samsung CF controller

This is v2 of the patchset adding support for Samsung's CF controller. 
Note: Depends on Ben Dook's platform_data helper patch

Changes since v1:

	- Made a seperate patch for plat-samsung changes
	- Moved CF true-ide configuration to driver code from
	  platform-specific setup code
	- Reduced memory allocated for CF device  
	- Renamed driver file to pata_samsung_cf.c
	- Used resource_size() function in ioremap
	- Used new dev_pm_ops

	- readl/writel functions consistently used
	- Used ata_pio_need_iordy, ata_timing_find_mode for setting up
	  pio mode instead of using own timing parameters
	- Removed useless checks in tf functions
	- Added overrides for sff_dev_select, sff_check_altstatus and
	  sff_set_devctl
	- Used platform_get_drvdata/platform_set_drvdata
	- Added request_mem_region which was missing 
	- Misc coding guideline changes - typos, extra includes,
	  parenthesis etc.

	- Changed the device naming override to follow onenand/iic style.

	- Removed the qc_prep override
	- Based the new patch on upstream branch of libata-dev

	- Used 'linux/gpio.h' in place of 'mach/gpio.h'
