[bsp] faster startup for cortex-a

2022-11-25T09:04:35Z

If the application defines dozens of global variables, the speed of clearing the bss segment will be slower. Because icache can be enabled before the mmu enabled. Therefore, in order to speed up the process of clearing the BSS segment, enable icache needs to be put ahead.

[update] Removed C++ global constructor initialization, this method is not used in GCC4.7 and later versions.
