aspeed: ast2500: Add lowlevel_init assembly

The original lowlevel_init function of AST2500 is written
in C. However, the C runtime environment is not ready until
_main execution.

This patch adds the assembly version of the lowlevel_init
function. Additional initialization to DRAM configuration
and LPC reset source are also added.
