console: allow to record console output before ready

Allow to record the console output before before U-Boot
has a console ready.

This patch allows to test the console output in sandbox test
based on console record.

It is possible because GD_FLG_RECORD and GD_FLG_SERIAL_READY
are 2 independent flags.
