The maximum SD clock frequency in High Speed mode is 50 MHz. This change
makes it possible to get 48 MHz from the USB PLL (240 MHz / 5 / 1)
instead of the previous 33.25 MHz from the AHB clock (133 MHz / 2 / 2).

As the lowlevel_init function is empty we should better
remove this assembly file entirely and use a dummy C
function instead.

Currently there is no support for MC34704 PMIC in the mainline kernel.
Turn on the LCD supply via bootloader for the time being, so that we could
use the LCD in the kernel.

The pmic_init() function has the I2C or SPI bus number that is connected to the
PMIC.
Instead of passing I2C_PMIC, explicitly pass the I2C bus number via I2C_x
definition.
The motivation for doing this is to avoid people just doing a copy and paste
of I2C_PMIC into their board file when another I2C bus is actually used to
interface to their PMIC.
This also makes more obvious which is the I2C bus connected to the PMIC, without
having to search in the source code for the meaning of the 'I2C_PMIC' number.

There is no change of behavior, even if some pad control values could probably
be simplified.

mx25pdk has a Ethernet port that is connected to its internal FEC controller.
In order to power up the Ethernet PHY (DP83640) it is necessary to communicate
with the MC34704 PMIC via I2C.
Make the FEC ethernet port functional

mx25pdk has a SD/MMC slot connected to esdhc1.
Add support for it and allow the environment variables to be saved into SD/MMC.
