Timur Tabi 6bd825f029 powerpc/85xx: use the BRx registers to enable indirect mode on the P1022DS
In order to enable the DIU video controller on the P1022DS, the FPGA needs
to be switched to "indirect mode", where the localbus is disabled and
the FPGA is accessed via writes to localbus chip select signals CS0 and CS1.

To obtain the address of CS0 and CS1, the platform driver uses an "indirect
pixis mode" device tree node.  This node assumes that the localbus 'ranges'
property is sorted in chip-select order.  That is, reg value 0 maps to
CS0, reg value 1 maps to CS1, etc.  This is how the 'ranges' property is
supposed to be arranged.

Unfortunately, the 'ranges' property is often mis-arranged, and not just on
the P1022DS.  Linux normally does not care, since it does not program the
localbus.  But the indirect-mode code on the P1022DS does care.

The "proper" fix is to have U-Boot fix the 'ranges' property, but this would
be too cumbersome.  The names and 'reg' properties of all the localbus
devices would also need to be updated, and determining which localbus device
maps to which chip select is board-specific.

Instead, we determine the CS0/CS1 base addresses the same way that U-boot
does -- by reading the BRx registers directly and mapping them to physical
addresses.  This code is simpler and more reliable, and it does not require
a U-boot or device tree change.

Since the indirect pixis device tree node is no longer needed, the node is
deleted from the DTS.

Timur Tabi 4a170d0198 powerpc/85xx: create 32-bit DTS for the P1022DS
Create a 32-bit address space version of p1022ds.dts.  To avoid confusion,
p1022ds.dts is renamed to p1022ds_36b.dts.  We also create p1022ds.dtsi
to store some common nodes.
