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

[libcpu][am335x] Fix the booting failure when enabling MMU
...
Since the 16 domains are configured as the client domains in
mmu_setttbase(), a Permission fault is generated if the XN bit
(Execute-never) is set in the short-descriptor translation table
(for section and supersection). This leads to the booting failure
when enabling MMU for beagleboard bsp. Here is log:
----------------------------------------------------------------
SD/MMC found on device 0

117 bytes read in 3 ms (38.1 KiB/s)

\## Starting application at 0x80200000 ...
----------------------------------------------------------------
This commit removes the XN bit configuration in the section of the
short-descriptor translation table. The OS can be booted successfully
with applying this commit.
