Add U-Boot-specific device tree overrides for the Genio 520 and 720 EVK
boards. These are needed to enable SD card support in U-Boot due to
current driver limitations. It is expected that these files will remain
after eventually converting these to CONFIG_OF_UPSTREAM, so we use
separate .u-boot.dtsi files for this.

mt8370_genio_510_evk_defconfig and mt8390_genio_700_evk_defconfig are
both based on MT8188, add a new mt8188.config file to share common
config.

Rename mt8390_evk to match the name of the device tree which is
mt8390-genio-700-evk.dts

Also update CONFIG_IDENT_STRING to be consistent.

David Lechner <dlechner@baylibre.com> says:

Before adding more targets, we take a moment to clean up some some
redundant code in existing Mediatek SoC support.

The first three patches are removing no-op functions. The last patch
generalizes the mem_map code so that it can be shared between all
Mediatek ARMv8 SoCs.
