dm: switch to 32bit kernel entry

Browse Source 
For the platform without virtual bootloader, dm will load uos kernel
directly, and hv will set rip according to uos kernel entry.

In current code, uos bsp starts from 64bit mode, so 64bit kernel entry
is used.

This patch series sets uos bsp to protected mode on such platform, so
32bit kernel entry is choosed.
