Yann Gautier 42beea8d70 stm32mp1: zeromem device_info struct
The change of the structure highlighted the fact that all fields are not
correctly initialized with zeroes.

Replace the other memset in the function with zeromem, as it is faster.

Yann Gautier 7ae58c6ba7 stm32mp1: use functions to retrieve some peripheral addresses
PWR, RCC, DDRPHYC & DDRCTRL addresses can be retrieved from device tree.
Platform asserts the value read from the DT are the SoC addresses.

Yann Gautier 6f4572bd78 Introduce timeout_init_us/timeout_elapsed() delay tracking with CNTPCT.
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].

Yann Gautier e0a8ce5d0d stm32mp1: remove some dependencies on clocks and reset in drivers
Include all RCC, clocks and reset headers from stm32mp1_def.h
which if exported to the firmware through platform_def.h.
The same dependency removal is done in common code as well.
Some useless includes are also removed in stm32_sdmmc2 driver.

Yann Gautier 3f9c97842e stm32mp1: make functions and macros more common
Mainly remove suffix 1 from prefix stm32mp1 in several macros and functions
that can be used in drivers shared by different platforms.

Yann Gautier c9d75b3cf9 stm32mp1: split code between common and private parts
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.
