The system configuration controller is mainly used to manage
the compensation cell and other IOs and system related settings.
The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.
Device tree files are also updated to manage vdd-supply regulator.

PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree.
Platform asserts the value read from the DT are the SoC addresses.

timeout_init_us(some_timeout_us); returns a reference to detect
timeout for the provided microsecond delay value from current time.
timeout_elapsed(reference) return true/false whether the reference
timeout is elapsed.
This change is inspired by the OP-TEE OS timeout resources [1].

Some parts of code could be shared with platform derivatives,
or new platforms.
A new folder plat/st/common is created to put common parts.
stm32mp_common.h is a common API aggregate.
Remove some casts where applicable.
Fix some types where applicable.
Remove also some platform includes that are already in stm32mp1_def.h.
