ARM: hisilicon: hikey: Fix eMMC with latest ATF & U-Boot

ATF can leave the MMC IP in a state where U-Boot mmc driver
can't enumerate the eMMC.

This patch provides a mmc0_reset_clk() function like we
already so do sd card controller which resets the IP
when entering U-Boot.

With this patch applied eMMC partitions are successfully
enumerated again.

ARM: hisilicon: hikey: Align memory node with upstream kernel

The memory node gets automatically generated by U-Boot
in arch_fixup_fdt(), before passing control to the kernel
using U-Boots representation of the dram banks.

However the upstream kernel uses the memory node to carve-out
regions of RAM for various purposes. To make this work without
changing arch_fixup_fdt() which will effect many platforms
we replicate the upstream memory node layout using the dram
banks.

ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.

Use DM for the pl01x serial driver on hikey. Also allow UART0 or
UART3 to be chosen via Kconfig.

By default we now output to UART3 as the latest version of ATF outputs
to this UART. Also UART3 comes out on the LS connector, as opposed to
UART0 which goes to a unpopulated header.

As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and
call the pinmux configuration code for the UART. Before we were
relying on ATF having already configured the pin configuration.

NB: Upstream Linux kernel doesn't yet support UART3, so serial console
will still be output on UART0 when booting a upstream kernel.

ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.

HiKey is the first 96boards consumer edition compliant board. It features a hi6220
SoC which has eight ARM A53 cpu's.

This initial port adds support for: -
1) Serial
2) eMMC / SD card
3) USB
4) GPIO

It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.

Notes:

eMMC has been tested with basic reading of eMMC partition into DDR. I have not
tested writing / erasing. Due to lack of clock control it won't be
running in the most performant high speed mode.

SD card slot has been tested for reading and booting kernels into DDR.
It is also currently configured to save the u-boot environment to the
SD card.

USB has been tested with ASIX networking adapter to tftpboot kernels
into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage
are correctly enumerated.

GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.
