arm: mvebu: add another earlyprintk Kconfig option
In order to support both old and new bootloaders, we add a new Kconfig option for the earlyprintk UART selection. The existing option allows to work with old bootloaders (that keep the internal registers mapped at 0xd0000000), while the newly introduced option allows to work with new bootloaders (that remap the internal registers at 0xf1000000).
