This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.
The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.
The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

This SD DMA function of i.MX28 is still apparently too experimental to be
enabled by default in 2012.04 release. Enable this feature only if the user
plans to tinker with DCache or explicitly enables it.

Phy autonegotiation works only when the ethernet cable is plugged in.
Since the phy was configured only at the init time, a plugged in cable
was necessary to initialize the phy properly.
This patch keeps a flag to check if the phy initialization has
succeeded, and calls configure_phy routine at every init if this flag
reports otherwise.

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.
Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"

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.
