soc/mediatek/mt8183: Share console for calibration blob output
Most coreboot debug messages are sent to UART and cbmem console, and we
also want to collect DRAM calibration module output, especially for
cbmem console (so we can see the logs after kernel is up).
Instead of sharing whole cbmem/cbtable/cbmemconsole implementations, we
want to simplify that by a simple function pointer so output can be
preserved by do_putchar, which internally sends data to all registered
consoles (usually cbmem console and UART).
BUG=b:139099592
TEST=make; boots properly for full-k, with and without serial console.
BRANCH=kukui
