ENGR00276832-4 epdc: port the driver to 3.10 kernel
merge the mach/epdc.h into linux/mxcfb_epdc.h
drop VM_RESERVED flag as deprecated.
drop VM_IO flag as it's automatically set in remap_pfn_range()
use <linux/platform_data/dma-imx.h> instead of <mach/dma.h>
use module_platform_driver()
add binding dts document for epdc fb driver
change the devname for interrupt from 'fb_dma' to 'epdc' to make it clear
