cr50: unlock console

Browse Source 
UART0 RX only needs to be disabled on reef. This change uses a system
property instead of a #define to disable UART0 RX that way it can just
be done on Reef not Gru or the dev board.

BUG=chrome-os-partner:55510
BRANCH=none
TEST=manual
	rw 0x4060000c shows a value of 1 for reef and 3 for gru

	gru kevin and reef still boot.

	Connect DIOA13 to DIOA1 on the dev board and verify the console
	can be used.
