This patch adds support for the Zipit Z2. The parts missing from this
patch are the battery support, SPI driver for the LCD and support for
the Silicon Serial ID chip.

CM-X300 bootloader passes DRAM configuration information in ATAGS,
however, the first memory bank is reported at actual physical address 0x8000000.
Use the configuration information supplied by the bootloader and
cope with the necessity to have PHYS_ADDR=0xa0000000.

REVISIT: change to GPIO18 is ugly, need to make sure whether that's
really necessary - GPIO18_RDY as an VLIO input signal - we don't
normally need to do such kind of trick during low power mode.

The assignments of res to the results of the two calls to
platform_get_resource make it impossible to use res in the error handling
code in the arguments to release_mem_region.

The semantic match that finds the former problem is as follows:

Try to keep minimum ifdef in ssp.h.  Some of the definitions are valid
only to specific SoCs, and device drivers should be responsible to take

PXA_SSP is actually used by drivers like drivers/spi/pxa2xx_spi.c and
sound/soc/pxa/pxa-ssp.c, not by boards. Remove those incorrect 'select'
from Kconfig and make SOC_PXA_SSP to select.

No need to separate them as they should be together from the begining.

The previous definitions of SSCR0_SCR and SSCR0_SerClkDiv() prevented
them being used simultaneously when supporting multiple PXA SoCs, esp.
in drivers/spi/pxa2xx_spi.c, make them correct.

The change from SSCR0_SerClkDiv(2) to SSCR0_SCR(2), will make the result
a little bit different in pxa2xx_spi_probe(), however, since that's only
used as a default initialization value, it's acceptable.

The corgi touchscreen is now deprecated in favour of the generic ads7846.c
driver. The noise reduction technique used in corgi_ts.c, which is to wait
till vsync before ADC sampling, is also integrated into ads7846 driver now.
Provided that the original driver is not generic and is difficult to maintain,
it will be removed now.

commit 672917dc ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.

Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis.  The fix is
simple, zero the variable after doing the work from the previous idle.

During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.
