nds32: Use the correct method to access registers

The registers are represented as bit arrays intended to be accessed using
the buf_set_* and buf_get_* functions. Storing the register values in
integers enables accessing them directly, which gives different results
depending on host byte order.

Convert the register store to use a byte array instead and fix all the
byte order bugs uncovered by that.

Also merge the 32 and 64 bit register fields. Only one of them is used at
a time and after the change to byte arrays their types are also the same.
