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
