Timing issue occurs on eMMC not only when modifying the frequency but
also for all the switch command(CMD6). According to the MMC spec waiting
8 clocks after a switch command would be the thing to do.
This patch allows fixing CPU hang observed when trying to changing the
bus width on a eMMC on SAMA5D4.

According to the Bananapro schematic VDD25-SATA either comes from a
dedicated WL2003E25-5 LTO, or it is connected to LDO4 via a
0 Ohm resistor.
In practice it seems that LDO4 is used, so enable it and set it to 2.5V.

Previously, AXP818 ALDO support was partially added to Kconfig, but
never enabled in the board file, nor properly set or configured in
Kconfig. The boards continue to work because the AXP818 is designed
to pair with the A83T/H8, and the default voltages match the reference
design's requirements.
