Add CONFIG_DELAY_CONSOLE to delay console init
This option delays console initialization until after relocation. This
can save time if this init is relatively expensive, since after
relocation the CPU is often running much faster.
This option should be used in conjunction with CONFIG_PRE_CONSOLE_BUFFER
to ensure that all console output is buffered until the console is
ready for it.
This saves about 30ms boot time.
