driver/ifc: Add 64KB page support
IFC has two register pages.Till IFC version 1.4 each
register page is 4KB each.But IFC ver 2.0 register page
size is 64KB each.IFC regiters structure is break into
two viz FCM and RUNTIME.FCM(Flash control machine) registers
are defined in PAGE0 and controls IFC generic functionality.
RUNTIME registers are defined in PAGE1 and controls NAND and
GPCM funcinality.
FCM and RUNTIME structures defination is common for IFC
version 1.4 and 2.0.
