Precedence: bulk

Some platforms, namely AMD Picasso, use non standard uart clocks (48M),
witch makes it impossible to use with earlycon.
    
Let the user select its own frequency.

Changes in v3:
- Revert patch to use kstrtouint for baudrate
- Parse the number not the ,number (Thanks Jiri :) )
- Add optional patch to increase the options size
- Link to v2: https://lore.kernel.org/r/20221123-serial-clk-v2-0-9c03ce8940d8@chromium.org

Changes in v2:
- Add a patch to fix handling of baudrate
- Use kstrtouint instead of simple_strtoul
- Link to v1: https://lore.kernel.org/r/20221123-serial-clk-v1-0-1f0554a46ad1@chromium.org
