nb/amd/pi/00730F01/northbridge: always return 1 in get_node_nums

This APU is always a single-node system and bits 4..6 of the node ID
register D18F0x60 are also marked as reserved in BKDG #52740 Rev 3.05.
On an APU2 board with quad-core APU, this register reads back 0x00030000
which results in a value of 1 to be returned from get_node_nums, so this
patch doesn't change behavior, but stops using reserved bits.

TEST=PC Engines APU2 still boots and doesn't show any new problems
