ARM: configs: stm32: Remove useless flags in STM32 defconfig

Browse Source 
As stm32_defconfig is dedicated to STM32 MCUs, disable
CONFIG_COMMON_CLK_STM32MP flag which is only used by STM32 MPUs.

Disable CONFIG_SUSPEND, CONFIG_ADVISE_SYSCALLS, CONFIG_IO_URING
CONFIG_POSIX_TIMERS, CONFIG_GCC_PLUGINS, it will reduce the kernel
image size for these platforms which embed a low amount of memory.

Tested on STM32F746-DISCO board which embeds 8MB of memory.
