[libcpu][C28x] Fix bugs of old c28x interrupt api which can not save and restore int status
...
In C28x DSP, interrupt status are stored in ST1 register. Both INTM and DBGM is used for masking interrupt, while the latter one is used in real-time debug mode. The origin function rudely enable and disable the interrupt without considering the recent interrupt status, which not only may cause problem in some situation but also is not in conformity with rt-thread design specifications. The new api will fix this bug.

avoid to conflicting types for 'uint32_t' error.
...
already uint32_t is defined at components/libc/compilers/minilibc/stdint.h.
there is two ways to solve, using <stdint.h>/uint32_t pair or
<rtthread.h>/rt_uint32_t pair.
I choose former because this code belongs to C compiler, not RT-Thread system.

[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
reading uEnv.txt
117 bytes read in 3 ms (38.1 KiB/s)
Loaded environment from uEnv.txt
Importing environment from mmc ...
Running uenvcmd ...
reading rtthread.bin
162624 bytes read in 24 ms (6.5 MiB/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.
