To handle STM32MP15 SOCs diversity, some updates have to been done.
This commit mainly adapt dk1 board to include the correct package and the
correct SOC version. A new file has been created to factorize common parts.

In order to cover the STM32MP15 SOCs family this commit updates pinctrl
file names (group definition and packages files).
This family includes: STM32MP151, STM32MP153 and STM32MP157.

On STM32MP1 EVAL and DISCOVERY boards, the SDMMC3 internal peripheral
can be used through the GPIO extension connector. The sdmmc3 node is then
added in the boards DT files, and the required pins are also added.
The node status is disabled as there is no device connected by default.

Add PWM support on stm32mp157a-dk1 board. There are several timers channels
made available on GPIO expansion and arduino connectors:
- Add PWM and trigger support (these timers can also be used as trigger
for ADC).
It's easier then to configure them all. But keep them disabled by default,
so the pins are kept in their initial state to lower power consumption.
This way they can also be used as GPIO.

Minimal value is the value set during boot or before suspend.
We must ensure that the value is a functional value to boot.

This patch adds support of STM32 PWR regulators on
stm32mp157c. This replace dummy fixed regulators on
stm32mp157c-ed1 and stm32mp157c-dk2.

DT validation ("make dtbs_check") has shown that some memory nodes were not
correctly written. This commit fixes this kind of issue:
"stm32f746-disco.dt.yaml: /: memory: False schema does not allow
{'device_type': ['memory'], 'reg': [[3221225472, 8388608]]}"

Configure ADC support on stm32mp157a-dk1. It can be used for various
purpose:
- AIN connector has several analog inputs: ANA0, ANA1, ADC2 in6 & in2,
ADC1 in13 & in6
- USB Type-C CC1 & CC2 pins wired to in18 & in19
It's easier then to Configure them all. But keep them disabled by default,
so the pins are kept in their initial state to lower power consumption.
This way they can also be used as GPIO.
Add VDD and VDDA supplies to ADC on stm32mp157c-dk1 board. This allows to
get full ADC analog performances in case VDDA is below 2.7V (not the case
by default).

Add support of Cirrus cs42l51 audio codec on stm32mp157a-dk1 board.
Configuration overview:
- SAI2A is the CPU interface used for the codec audio playback
- SAI2B is the CPU interface used for the codec audio record
- SAI2A is configured as a clock provider for the audio codec
- SAI2A&B are configured as slave of the audio codec
- SAI2A&B share the same interface of the audio codec
Note:
In master mode, cs42l51 audio codec provides a bitclock
at 64 x FS, regardless of data width. This means that
slot width is always 32 bits.
Set slot width to 32 bits and slot number to 2
in SAI2A&B endpoint nodes, to match this constraint.
dai-tdm-slot-num and dai-tdm-slot-width properties are used here,
assuming that i2s is a special case of tdm, where slot number is 2.

On disco and eval board, Tx and Rx delay are applied (pull-up of 4.7k
put on VDD) so which correspond to RGMII-ID mode with internal RX and TX
delays provided by the PHY, the MAC should not add the RX or TX delays
in this case

Four packages exist for stm32mp157 die. As ball-out is different between
them, this patch covers those differences by creating dedicated pinctrl
dtsi files. Each dtsi pinctrl package file describes the package ball-out
through gpio-ranges.
stm32mp157a-dk1 / dk2 boards embed a STM32MP_PKG_AC (TFBGA361 (12*12))
package.
stm32mp157c-ed1 / ev1 boards embed a STM32MP_PKG_AA (LFBGA448 (18*18))
package.

This patch adds stpmic1 support on stm32mp157a dk1 board.
The STPMIC1 is a PMIC from STMicroelectronics. The STPMIC1 integrates 10
regulators, 3 power switches, a watchdog and an input for a power on key.
The DMAs are disabled because the PMIC generates a very few traffic and
DMA channels may lack for other usage.
