Allowing console base address to be set to NULL conveniently allows console driver to ignore further invocations to console_putc() and console_getc(). This patch adds `console_uninit()` API to the console driver which sets console base address as NULL. The BL images can invoke this API to finish the use of console and ignore any further invocations to print to the console. Change-Id: I00a1762b3e0b7c55f2be2f9c4c9bee3967189dde
