mpc83xx: Add support for the MPC8349E-mITX

PREREQUISITE PATCHES:

* This patch can only be applied after the following patches have been applied:

  1) DNX#2006090742000024 "Add support for multiple I2C buses"
  2) DNX#2006090742000033 "Multi-bus I2C implementation of MPC834x"
  3) DNX#2006091242000041 "Additional MPC8349 support for multibus i2c"
  4) DNX#2006091242000078 "Add support for variable flash memory sizes on 83xx systems"
  5) DNX#2006091242000069 "Add support for Errata DDR6 on MPC 834x systems"

CHANGELOG:

* Add support for the Freescale MPC8349E-mITX reference design platform.
  The second TSEC (Vitesse 7385 switch) is not supported at this time.

means it is 0 when the IRQ is not active. This makes the wire-AND
logic always assert IRQ7 to CPU even if there is no request from the
switch. Since the compact flash and the switch share the same IRQ,
the Linux kernel will think that the compact flash is requesting irq
and get stuck when it tries to clear the IRQ. Thus we need to set
the L2_IRQ0 and L2_IRQ1 to active low.
The following code sets the L1_IRQ and L2_IRQ polarity to active low.
Without this code, compact flash will not work in Linux because
unlike U-Boot, Linux uses the IRQ, so this code is necessary if we

/**
* Program a UPM with the code supplied in the table.
*
* The 'dummy' variable is used to increment the MAD. 'dummy' is
* supposed to be a pointer to the memory of the device being
* programmed by the UPM. The data in the MDR is written into
* memory and the MAD is incremented every time there's a read
* from 'dummy'. Unfortunately, the current prototype for this
* function doesn't allow for passing the address of this
* device, and changing the prototype will break a number lots
* of other code, so we need to use a round-about way of finding
* the value for 'dummy'.
*
* The value can be extracted from the base address bits of the
* Base Register (BR) associated with the specific UPM. To find
* that BR, we need to scan all 8 BRs until we find the one that
* has its MSEL bits matching the UPM we want. Once we know the
* right BR, we can extract the base address bits from it.
*
* The MxMR and the BR and OR of the chosen bank should all be
* configured before calling this function.
*
* Parameters:
* upm: 0=UPMA, 1=UPMB, 2=UPMC
* table: Pointer to an array of values to program
* size: Number of elements in the array. Must be 64 or less.
