ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from <mach/memory.h>
The platforms selecting NEED_MACH_MEMORY_H defined the start address of
their physical memory in the respective <mach/memory.h>. With
ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless
though because the definition isn't used but determined dynamically.
So remove the definitions from all <mach/memory.h> and provide the
Kconfig symbol PHYS_OFFSET with the respective defaults in case
ARM_PATCH_PHYS_VIRT isn't enabled.
This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H
which prevents compiling an integrator nommu-kernel.
(CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to
"0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects
NEED_MACH_MEMORY_H.)

ARM: use ARM_DMA_ZONE_SIZE to adjust the zone sizes
Rather than each platform providing its own function to adjust the
zone sizes, use the new ARM_DMA_ZONE_SIZE definition to perform this
adjustment. This ensures that the actual DMA zone size and the
ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS definitions are consistent with
each other, and moves this complexity out of the platform code.

ARM: Replace platform definition of ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS
The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is
the physical/bus address, the other is the virtual address. Both need
to be kept in step, so rather than having platforms define both, allow
them to define a single macro which sets both of these macros
appropraitely.

[ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing. What
most platforms are using is bus_addr == phys_addr so such is the default.
One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation. Also
added a comment about the special footbridge bus translation.
Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.
