fluid-mnf/target-bin/cmd39.m0: hand-crafted by copying cmd.m0 and manually patching the S3 record that contains the 16-bit word at 0x1140, the literal pool DPLL init constant used by hardware_init_calypso()

Reading the ASIC_CONF_REG, IO_CONF_REG and IO_CNTL_REG registers via ETM when
the firmware is running shows the same values that are set by the Init_Target()
code we have disassembled.

When the firmware is running, reading the ARMIO_LATCH_OUT register via ETM
returns 0x3F07, i.e., GPIO outputs 0, 1 and 2 (RI, DSR, DCD) are 1s, meaning
modem control signals inactive.

APCOFF register setting in the Iota ABB is 0x070, same as in our reference fw.
