Subject: earlycon: Increase options size

earlycon: Increase options size

Now that the clock frequency is also part of the options, 16 bytes is
too little.

Without this patch dmesg does not show the whole options, Eg:

earlycon: uart0 at MMIO32 0x00000000fedc9000 (options '115200n8,480000')

instead of: '115200n8,48000000'
