twl4030: fix potential power supply handling issues

twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively

write fails.

Fix this by writing vsel first and device group after that. Also

the voltage, and start logging errors as power supply problems are

This is needed to support Freescale-supplied userspaces.

At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

imximage: Remove overwriting of flash_offset

The flash header supports different flash offsets for different
boot devices. E.g. parallel NOR or OneNAND use a different offset
than FLASH_OFFSET_STANDARD (== 0x400).

The flash offset is correctly read from the configuration in
parse_cfg_cmd(). But is then overwritten wrongly in set_imx_hdr_v1/2().

Fix this by removing this overwriting. Use the flash offset
correctly read from the configuration, instead.

If there is no flash_offset read from the configuration file, i.e.
the BOOT_FROM tag is missing, exit with an error message.
