This patch adds USB HS support in host mode only.
This port supports OTG mode, but the device more is not working
properly as of now.
Once the device mode fixed, the node will be updated to support OTG.

All the clocks referenced by the GPIO banks were not the good ones.

STM32F429 allows to remap FMC SDRAM Bank 1 from 0xc0000000 to 0x0,
by writing 0x4 to SYSCFG_MEMRMP register.
As mentionned in the reference manual (see chapter 9.3.1), the performance
gain is really interresting:
"In remap mode at address 0x0000 0000, the CPU can access the external
memory via ICode bus instead of System bus which boosts up the
performance."
These are the dhrystone results with and without the remap enabled:
Default (SDRAM in 0xc0000000):
---------------------------------
Microseconds for one run through Dhrystone: 31.8
Dhrystones per Second: 31416.9
Remap (SDRAM in 0x0000000):
-----------------------------
Microseconds for one run through Dhrystone: 20.6
Dhrystones per Second: 48520.1
This patch first change the SDRAM start address to 0x0 for STM32429i-EVAL
board, and also set the dma-range property as the other masters than the M4
CPU still see SDRAM in 0xc0000000.
Note that the Discovery board cannot benefit from this feature, since the
SDRAM is connected to Bank 2.

New bindings and driver have been created for STM32F42xxx series parts.
This patch integrates these changes.
Note: Earlier device tree blobs (those without st,stm32f42xxx
compatibles for the rcc) could still be used to boot basic
systems. Such systems rely on the bootloader to configure the
clock gates for vital periperhals.
