Platform specific code for MPC5121 USB Host support.
MPC5121 Rev 2.0 silicon EHCI registers are big endian.
Add appropriate support by specifying fsl,big-endian-regs
property in device tree node for USB controller. Also
allow specifying DRVVBUS and PWR_FAULT signal polarity

MPC5121 DIU configuration/setup as initialized by the boot
loader currently will get lost while booting Linux. As a
result displaying the boot splash is not possible through
the boot process.
To prevent this we reserve configured DIU frame buffer
address range while booting and preserve AOI
Collects several changes needed after applying
previous mpc5121 platform and driver patches:
- Add mpc5121 reset module node
- Clean up and fix NAND description, remove unused properties
here and correct NAND flash chip size.
- Clean up I2C nodes: remove obsolete cell-index properties,

After kfifo rework it's no longer possible to reliably know if kfifo is
usable, since after kfifo_free(), kfifo_initialized() would still return
true. The correct behaviour is needed for at least FHCI USB driver.
This patch fixes the issue by resetting the kfifo to zero values (the
same approach
