ARM: Fix start.S when used with SPL in arm1136

This patch modifies start.S for the arm1136 to make it
conform to start.S  in armv7 architecture, to make it
usable if the SPL framework is used.

MX35: add support for woodburn board

The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the
generic SPL framework to implement the internal boot
mode.

The following peripherals are supported:
- Ethernet (FEC)
- SD Card
- NAND (512 MB)
- NOR Flash

In the internal boot mode, a simple imximage header
is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.

mx25pdk: Include CONFIG_MX25

It is necessary to include CONFIG_MX25 as several i.mx drivers handle the SoC

pmic_fsl: Introduce FSL_PMIC_I2C_LENGTH

Introduce FSL_PMIC_I2C_LENGTH to configure the number of bytes that are used to
communicate with the PMIC via I2C.

Instead of hardcoding the value, pass the number via a configurable option per
PMIC type.

This will be useful for adding support for PMIC MC34704 from Freescale, which
uses only one byte in its I2C protocol.

ipu common: reset ipuv3 correctly

This patch checks self-clear sw_ipu_rst bit in
SCR register of SRC controller to be cleared
after setting it to high to reset IPUv3. This
makes sure that IPUv3 finishes sofware reset.
A timeout mechanism is added to stop polling
on the bit status in case the bit could not be
cleared by the hardware automatically within
10 millisecond.
