[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.
