lib: sbi: Fix non-root domain startup

Browse Source 
Currently, the sbi_sse_init() in cold boot path is called after
sbi_domain_finalize() so boot HART of non-root domains will start
before SSE cold boot init which can cause warm boot of such HARTs
to crash in sbi_sse_init().

To address the above issue, factor-out the non-root domain startup
from sbi_domain_finalize() function as a separate sbi_domain_startup()
function  which can be called after sbi_sse_init() in cold boot path.
