fcup-settime: moved time() retrieval a little closer to the output
A fundamental problem with all simple time transfer tools is that there is
always some delay between the time retrieval on the source system and that
transmitted time being set on the destination, and the resulting time
on the destination system is off by that delay amount. This delay cannot
be fully eliminated when working in a simple environment like ours,
but we should make our best effort to minimize it. In the present case,
moving the atinterf_init() call before the time() retrieval should make
a teensy-tiny improvement.

# The RAM+flash MCP in the GTA02 GSM modem block is SEC K5A3281CTM. # The closest datasheet that could be found is for K5A3280; # all current understanding of this IC is based on the latter datasheet. # OsmocomBB sets WS=3 for both nCS0 and nCS1. At first I was concerned that # the setting was wrong for nCS0, but I have now located the responsible # code in the moko11 binary (see the moko11 notes file in the # freecalypso-reveng Hg tree) and confirmed that the official firmware # runs with the same settings. So let's do likewise. w16 fffffb00 00A3 w16 fffffb02 00A3
