ppc4xx clear_bss() fails if BSS segment size is not
divisible by 4 without remainder. This patch provides
fix for this problem.

flush + invalidate_dcache_range() expect the start and stop+1 address.
So the stop address is the first address behind (!) the range.

By using aliases in the dts file, the ethernet node fixup is
much easier with the recently added functions.
Please note that the dts file needs the aliases for this to work.

As reported by Gerhard Berghofer:
in "gpio_enable_usart3" the correct pins for USART 3 are PB17 and PB18
instead of PB18 and PB19.
which is obviously correct. There's currently no code that uses
USART3, but custom boards may run into problems.

Add a chip-features file providing definitions of the form
AT32AP700x_CHIP_HAS_<peripheral>
to indicate the availability of the given peripheral on the currently
selected chip.

The SoC-specific code for all the AT32AP700x CPUs is practically
identical; the only difference is that some chips have less features
than others. By doing this rename, we can add support for the AP7000
derivatives simply by making some features conditional.

The MPC8572 introduces the concept of an asynchronous DDR clock with
regards to the platform clock.
Introduce get_ddr_freq() to report the DDR freq regardless of sync/async
mode.

Move to using CFG_MPC85xx_*_ADDR as the base of the registers
instead of getting it via &immap.

Ugh. I *hate* to back this change out, but these compiler flags don't
work for relocation on all versions of GCC. I've not been able to
reproduce the environment in my setup (and hence, not been able to
find a combination that *does* work), so I've got no choice but to go
back to the old gcc flags and linker script.

Most 4xx PPC capable of using an I2C bootrom for bootstrap setting
already print a line with the information which I2C bootrom is
used for bootstrap configuration. So we don't need this extra line
with "I2C boot EEPROM en-/dis-abled".
This patch also has a little code cleanup integrated.
