[U-Boot] [PATCH v2 20/47] efi: Avoid using non-existent text base

From: Ben Stoltz <stoltz at google.com>

When U-Boot runs as an EFI application is does not have a definition of
CONFIG_SYS_TEXT_BASE. U-Boot is a relocatable application and the relocation
is done by EFI. U-Boot can be loaded at any address.

This is similar to how sandbox works. Adjust the early board init to deal
with this.
