vikram pandita d9f5007491 omap: introduce OMAP_LL_DEBUG_NONE DEBUG_LL config
Zoom2/Zoom3 kind of boards do not use omap uarts for console.
These use external debug board for console.

So these boards should not have "Uncompressing Kernel...."
log put on omap uarts.

By interoducing OMAP_LL_DEBUG_NONE option,
unnecessary writes to omap uarts is avoided.

In future, the DEBUG_LL interface will be enhanced
to use external debug board.

Say Y if you want to reset unused clocks during boot.
This option saves power, but assumes all drivers are
using the clock framework. Broken drivers that do not
yet use clock framework may not work with this option.
If you are booting from another operating system, you
probably do not want this option enabled until your
device drivers work properly.

This timer saves power compared to the OMAP_MPU_TIMER, and has
