The nios2-io.h defines hardware registers and bits of several FPGA IP cores. It could be divided in to the specific drivers, including altera timer, altera sysid, altera uart and altera jtag uart. The altera pio and altera spi drivers use their own hardware definitions. The removal of nios2-io.h will help modularity and maintenance. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>
