p2020ds: add alternate boot bank support using the ngPIXIS FPGA
The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS.
The ngPIXIS has one distinct new feature: the values of the on-board switches
can be selectively overridden with shadow registers. This feature is used to
boot from a different NOR flash bank, instead of having a register dedicated
for this purpose. Because the ngPIXIS is so different from the previous PIXIS,
a new file is introduced: ngpixis.c.
Also update the P2020DS checkboard() function to use the new macros defined
in the header file.
