twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively
enabling the supply), and only then sets vsel (selects voltage). This could
lead to wrong voltage for a short time, or even long time if second i2c
write fails.
Fix this by writing vsel first and device group after that. Also
introduce error checking to not enable the supply if we failed to set
the voltage, and start logging errors as power supply problems are
usually important.

The patch below fixes device enumeration through the U-Boot API.
Device enumeration crashes when the system in question doesn't
have any RAM mapped to address zero (I discovered this on a
BeagleBone board), since the enumeration calls get_dev with a
NULL ifname sometimes which then gets passed down to strncmp().
This fix simply ensures that get_dev returns NULL when invoked
with a NULL ifname.

Change the parent UART clock to be PLL2, so that U-boot can also boot
a Freescale 2.6.35 kernel for mx53.
FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid
conflicts with IPU clocks, so that the video resolution can be changed
without affecting the UART clock.
On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded
and this patch fixes this problem.
Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.
