A /etc/init.d/gsmd  works for me on boot

After a lot of analysis, there are some conclusions. 
1. In GTA01v3 because of uart between modem and CPU and debug uart are the
   a.  u-boot has to remove "console=/dev/ttySAC0,115200" parameter 
   b. The initiate message from GSM modem will be po luted
   c. Uart /dev/ttySAC0 has to be reset

2. Observing the behaviour of uart, GTA01v3 goes wrong when function "select"
called for the first open. It has to be close and reopen and so that it can
behave well

So a easy way that GSMD can initialize well is open it twice at the
/etc/init.d/gsmd start

Note. libmokogsmd shall not restart gsmd with this script. (Only do this when
gsmd is actually dead.)
