Usage of labels instead of full paths reduces possible mistakes when
overriding nodes.

HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards. This also adds RCLK GPIO line,
this gpio should be in pull-down state.
This also enables HS400 on peach-pi and this updates the clock
frequency to 800MHz to be set as input clock to controller.

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.
Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:
* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]
The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.
But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.
It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.
Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".

This patch adds the mmc device tree node entries for exynos5420 SOC.
Exynos5420 has a different version of DWMMC controller,so a new
