438ff3f3cc [AVR32] Add support for AT32AP7001 and AT32AP7002
These are derivatives of the AT32AP7000 chip, which means that most of
the code stays the same. Rename a few files, functions, definitions
and config symbols to reflect that they apply to all AP700x chips, and
exclude some platform devices from chips where they aren't present.

82c54f864f [AVR32] ngw100 i2c-gpio tweaks
Make the NGW100 bitbang i2c use open drain signaling.

Also, speed it up, so it's closer to 100 kHz ... the code paths seem
to be long enough that the udelay isn't dominating bit times.  The
peak bit rate I observed was around 125 kHz, but that's with large
delays (usually before ACK/NAK) which hold the overall rate down to
around 80 kHz (call it 100 usec/byte on average).

af8184718a [AVR32] SMC configuration in clock cycles
This patch makes the SMC configuration take timings in clock cycles
instead of nanoseconds. A function to calculate timings in clock
cycles is added.

This patch removes the rounding troubles of the previous SMC
configuration method.

54bb69e250 [AVR32] Wire up i2c-gpio on the ATNGW100 board
The NGW100 has a board controller which is hooked up to the TWI lines
on AP7000. Since the TWI driver isn't in mainline, use the i2c-gpio
driver in the mean time.

7f8b9acae8 [AVR32] NGW100, Remove relics of the old USART mapping scheme
USART mapping used to be accomplished by the manual filling of
at32_usart_map[] and at32_nr_usarts.  This has now been replaced
with at32_map_usart() so we can remove these variables.
