This commit adds driver for Exynos54xx ADC subsystem.
The driver is implemented using driver model, amd provides
ADC uclass's methods for ADC single channel operations:
- adc_start_channel()
- adc_channel_data()
- adc_stop()
The basic parameters of ADC conversion, are:
- sample rate: 600KSPS
- output the data as average of 8 time conversion
ADC features:
- sample rate: 600KSPS
- resolution: 12-bit
- channels: 10 (analog multiplexer)

This commit adds:
- new uclass id: UCLASS_ADC
- new uclass driver: drivers/adc/adc-uclass.c
The new uclass's API allows for ADC operation on:
* single-channel with channel selection by a number
* multti-channel with channel selection by bit mask
ADC uclass's functions:
* single-channel:
- adc_start_channel() - start channel conversion
- adc_channel_data() - get conversion data
- adc_channel_single_shot() - start/get conversion data
* multi-channel:
- adc_start_channels() - start selected channels conversion
- adc_channels_data() - get conversion data
- adc_channels_single_shot() - start/get conversion data for channels
selected by bit mask
* general:
- adc_stop() - stop the conversion
- adc_vdd_value() - positive reference Voltage value with polarity [uV]
- adc_vss_value() - negative reference Voltage value with polarity [uV]
- adc_data_mask() - conversion data bit mask
The device tree can provide below constraints/properties:
- vdd-polarity-negative: if true: Vdd = vdd-microvolts * (-1)
- vss-polarity-negative: if true: Vss = vss-microvolts * (-1)
- vdd-supply: phandle to Vdd regulator's node
- vss-supply: phandle to Vss regulator's node
And optional, checked only if the above corresponding, doesn't exist:
- vdd-microvolts: positive reference Voltage [uV]
- vss-microvolts: negative reference Voltage [uV]

Some devices are supplied by configurable regulator's output.
But there was no function for getting it. This commit adds
function, that allows for getting the supply device by it's phandle.
The returned regulator device can be used with regulator uclass's API.

This driver allows I/O operations on the Samsung S2MPS11 PMIC,
which provides lots of LDO/BUCK outputs.
To enable it, update defconfig with:
- CONFIG_PMIC_S2MPS11
and additional, if were not defined:
- CONFIG_CMD_PMIC
- CONFIG_ERRNO_STR

The proper CPU ID for those Exynos variants is 0x5422,
but before the 0x5800 was set. This commit fix this back.
Changes:
- set cpu id to 0x5422 instead of 0x5800
- remove macro proid_is_exynos5800()
- add macro proid_is_exynos5422()
- change the calls to proid_is_exynos5800() with new macro

The CPU name for Exynos was concatenated with cpu id,
but for new Exynos platforms, like Chromebook Peach Pi
based on Exynos5800, the name of SoC variant does not
include the real SoC cpu id (0x5422).
For such case, the CPU name should be defined in device tree.
This commit introduces new device-tree property for Exynos:
- "cpu-model" - with cpu name string
If defined, then the cpu id is not printed.

As sama5 board has 32k sram size, so the at91bootstrap and spl for sama5
boards is bigger than 16k (0x4000). That will overlap the U-Boot

well.

After silencing the prints which were generated when reconfiguring the
clock of the SD/MMC bus, surprisingly, the driver stopped working such
that every attempt to use the SD/MMC bus caused the CPU to get totally
stuck hard. It turns out that the prints generated a short delay, which
was necessary for the CPU to reconfigure the clock without getting stuck.
Thus, this patch adds a short delay after the clock configuration instead.

This driver generates clearly debugging prints when changing clock
speed, so silence those. Furthermore, the driver generates further
prints in case a command fails to complete. The later case woud be
useful, but for eMMC, command 8 can fail and it's not an error but
a part of the specification. Thus, make this debug() as well.
