[ARM] 5611/1: ep93xx: update ts72xx nor flash support 

Update the NOR flash support for TS-7200.

The TS-7200 models all have 16-bit NOR flash.  Update the platform
init to support this.

Remove the private TS72XX_NOR_* defines and use the common ep93xx
defines for the external chip select physical base address instead.

Move the NOR flash registration into a static __init function.  When
the NAND flash support is updated this function will also be used
to register the NAND flash for the TS-7250 and TS-7260.
