The L2x0 cache controllers need to explicitly drain their write buffer
even for Normal Noncacheable memory accesses.

This patch introduces the outer_cache_fns.sync function pointer together
with the OUTER_CACHE_SYNC config option that can be used to drain the
write buffer of the outer cache.

To avoid #include collisions with subsequent patches in the series, this
patch moves the outer_cache definitions to a separate asm/outercache.h

According to imx31 reference manual the signal from external low

The patch makes redundant the previously defined mxc_rtc clock.

The function locomo_m62332_senddata sends a three byte i2c message to
a M62332 DAC. This entire function is guarded with a spin_lock_irqsave
at the start of the function and a spin_unlock_irqrestore at the end.
As each byte is transferred, the i2c ACK from the DAC is checked.
Currently, if the ACK is missing the function simply returns without
the unlock. It also leaves the i2c bus in an invalid state since the
last byte transferred did not have a "stop" condition and leave the
bus idle.
Fix this by adding an exit path using goto.

The locomo spi registers are all defined in locomo.h as offsets
from the first spi register LOCOMO_SPI (0x60), which is itself
an offset from the locomo base address. To correctly access
these registers LOCOMO_SPI must always be included in the
address calculation.
There are two places in locomo.c where this is not done. The
first one, in locomo_suspend, actually results in a write to
LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe
and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE.
Fix these by including LOCOMO_SPI in the calculation.

This looks cleaner and allows us to call mx51_revision

This is for protecting a wrong mapping attempt of a zero-based
physical address.
The result is that, no serial port will be attempted to be mapped.
Also add an additional protection for NULL clocks before attempting
to enable them (if above condition applies)
