747c4c68c0 stm32: Correct positioning of declaration
The current code gives a warning:

arch/arm/mach-stm32/stm32f7/soc.c: In function 'arch_cpu_init':
arch/arm/mach-stm32/stm32f7/soc.c:38:2: error: 'for' loop initial
    declarations are only allowed in C99 or C11 mode
  for (int i = 0; i < ARRAY_SIZE(stm32_region_config); i++)
  ^
arch/arm/mach-stm32/stm32f7/soc.c:38:2: note: use option -std=c99,
    -std=gnu99, -std=c11 or -std=gnu11 to compile your code

Fix it by moving the declaration to the top of the function.

624b7101ee stm32f7: configure mpu valid for f7 family
This configuration should be valid for all F7 family devices in general.
Here is the regions info:

	- Region0 : 4GB	  : cacheable & executable.
	- Region1 : 512MB : text area	: strogly ordered & executable.
	- Region2 : 512MB : peripherals : device memory & non-executable.
	- Region3 : 512MB : peripherals : device memory & non-executable.
	- Region4 : 512MB : cortexM area: strongly ordered & non-executable.

Higher region number overrides the lower region configuration.
