cmd: cpu: fix NULL cpu feature prints

Commit 740d5d3 added two new features but only one feature name,
which results in NULL prints when device_id feature is selected.

Before:
	HG556a # cpu detail
	 -1: cpu@0	BCM6358A1
		ID = 0, freq = 300 MHz: L1 cache, MMU, NULL
		Device ID 0x2a010
	 -1: cpu@1	BCM6358A1
		ID = 1, freq = 300 MHz: L1 cache, MMU, NULL
		Device ID 0x2a010
After:
	HG556a # cpu detail
	 -1: cpu@0	BCM6358A1
		ID = 0, freq = 300 MHz: L1 cache, MMU, Device ID
		Device ID 0x2a010
	 -1: cpu@1	BCM6358A1
		ID = 1, freq = 300 MHz: L1 cache, MMU, Device ID
		Device ID 0x2a010
