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.

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.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

With dynamic debug having gained the capability to report debug messages
also during the boot process, it offers a far superior interface for
debug messages than the custom cpufreq infrastructure. As a first step,
remove the old cpufreq_debug_printk() function and replace it with a call
to the generic pr_debug() function.
How can dynamic debug be used on cpufreq? You need a kernel which has
CONFIG_DYNAMIC_DEBUG enabled.
To enabled debugging during runtime, mount debugfs and
$ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control
for debugging the complete "cpufreq" module. To achieve the same goal during
boot, append
ddebug_query="module cpufreq +p"
as a boot parameter to the kernel of your choice.

Several Davinci platforms select the I2C EEPROM support, but don't
select I2C support. This causes I2C EEPROM support to be built into
the kernel, but I2C support may not be configured to be built in.
This leads to linker errors due to missing I2C symbols.
Arrange for I2C to be selected whenever EEPROM_AT24 is selected.

The MUSB driver doesn't see its platform device on DM644x EVM board anymore
since commit 73b089b052 (usb: musb: split davinci
to its own platform_driver) because the new probe is called as subsys_initcall()
now, and the device is registered later than that by the board code. Move the
registration to davinci_evm_init() -- it's safe to do so because the MUSB core
device still gets initialized as fs_initcall() -- which is late enough for the
I2C GPIO expander (which controls VBUS) to be initialized.
