This filename conflicts with the 'mbedtls' package. They are renamed
in the name of the corresponding chips and included in 'board.h'.
Files that rely on this file should include 'board.h' instead.

修正am335x中mmu问题

1) mmu_disable_dcache/mmu_enable_dcache等, 应使用rt_cpu_xxx相关函数,否则会跑飞. armcc并没有提供rt_cpu_xxx对应汇编代码,先删除
2) mmu_setmtt抽取为函数mmu_setmtts,并增加RT_WEAK.mmu_setmtts此处作为示例函数.实际用户板子可在bsp中重新实现该函数.可在rt_components_board_init函数前调用rt_hw_mmu_init
