EARLY_PRINTK_BAUD is not necessary as we don't use the initialization
function (EARLY_PRINTK_INIT_UART is not set).

With the EARLY_PRINTK_BAUD dropped, this could be merged with the
xgene-storm  early printk (I didn't really understand why the baud rate
is different). But I don't think it's 4.5 material.
