ARM: OMAP1: Fix DEBUG_LL and earlyprintk on OMAP16XX

Browse Source 
[ Upstream commit 7e74b606dd ]

On OMAP16XX, the UART enable bit shifts are written instead of the actual
bits. This breaks the boot when DEBUG_LL and earlyprintk is enabled;
the UART gets disabled and some random bits get enabled. Fix that.
