HV: Replace printf with pr_acrnlog after logmsg init

Browse Source 
There are some massages which is not fatal error but should to print
to serial and sbuf(hvlog) at the same time. pr_fatal is for fatal error
massages and it is not good choice for the situation above.

Introduce a new API pr_acrnlog to deal with the situation. And replace the
following printf with pr_acrnlog for massages should be print to sbuf and
serial. Then developers can get those massages on serial and BTM(Boot Time
Measurement) can use acrnlog to get those massages from sbuf.

BTM refers to Boot Time Measurement which will read acrnlog file to get
timestamps of steps we want.
