Rewrite the mxc_i2c driver.
* This version is much closer to Linux implementation.
* Fixes IPG_PERCLK being incorrectly used as clock source
* Fixes behaviour of the driver on iMX51
* Clean up coding style a bit ;-)

The PLL decoding algorithm didn't take into account many configuration bits.
Adjust it according to Linux kernel. Also, add PLL4 for MX53.

This patch allows user to register multiple FEC controllers. To preserve
compatibility with older boards, the mxcfec_register() call is still in place.
To use multiple controllers, new macro is in place, the mxcfec_register_multi(),
which takes more arguments. The syntax is:
mxcfec_register_multi(bd, FEC ID, FEC PHY ID on the MII bus, base address);
To disable the fecmxc_register() compatibility stuff, define the macro
CONFIG_FEC_MXC_MULTI. This will remove the requirement for defining IMX_FEC_BASE
and CONFIG_FEC_MXC_PHYADDR.

The default is MII100, which was hardcoded previously in the driver.

This magic constant with zero documentation, when it's last 8 bits are set to
0x45, configures correctly the PERCLK dividers. Therefore the I2C operates
correctly when divider computed from PERCLK.
Note: This constant is written to CBCDR register in
arch/arm/cpu/armv7/mx5/lowlevel_init.S, but it's written only once. The register
is accessed three more times in the file, with different values written to it
each time.

Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes.
Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt
and there was no activity, the system entered into idle mode while watchdog timer was still active.
Fix this by disabling watchdog timer during idle mode.

Currently the reset cause is printed like:
CPU: Freescale i.MX31 rev 2.0 at 531 MHz.Reset cause: POR
Improve readability by adding a new line like it is done on other i.MX boards.
