dts: stm32: refine STM32MP15 secure/non-secure I2C4 pinctrl states

Explicitly state that legacy pinctrl phandles i2c4_pins_a and
i2c4_sleep_pins_a refer to non-secure I2C4 pin muxing on STM32MP15
based platforms.

Define secure I2C4 bus pinctrl states for boards that use the I2C4 bus
in secure state on STM32MP15 SoCs.

ETZPC node useless in non-secure Linux kernel but needed by secure
world.

RCC node remains disabled for the secure side so that RCC TZ
hardening is disabled since mainline Linux kernel and U-Boot
do not support SCMI clocks and reset domains. IWDG1, ETZPC, STGEN
and CRYP1 devices are described to ease their later integration.
