xiaoguang_ma 16f6157b1e [bsp] faster startup for cortex-a 
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.

zhouji 42ce237dc9 [update] 整理cortex-a aarch32启动代码 
1. 去除start_gcc.s中set_secondary_cpu_boot_address代码，这部分提取到qemu-vexpress-a9 bsp中。
2. 移动cpu.c中rt_hw_cpu_id函数到cp15_gcc.s，使用汇编实现，采用wake属性，方便bsp根据cpu特性获取CPU ID（多cpu集群中，不同厂家使用组合不一样）.
3. 整理start_gcc.s 适应多核启动，原来的代码只考虑到双核的情况。
