Having a RTC that doesn't maintain proper time across a reboot is one
thing. But a RTC that doesn't work at all and only causes timeouts is
another.

This patch modifies invalid time handling in the
SuperH RTC driver. Instead of zeroing the returned
value at read-out time we just return an error code
and reset invalid values during probe.

This patch modifies the SuperH RTC driver to only
enable carry interrupts when needed. So by default
no interrupts are enabled with this patch. Without
this patch a suspending system will most likely
wake up by the carry interrupt regardless if the
alarm interrupt has been enabled or not.

The remaining registers are separated into:
- <mach/regs-ost.h>
- <mach/regs-rtc.h>
- <mach/regs-intc.h>
and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:
1. include the specific <mach/regs-*.h> with care (if that's absolutely
necessary)
2. define the registers in the driver, make cleanly defined API to expose
the register access to external with sufficient reason

Add support for single IRQ hardware to the sh-rtc driver.
This is useful for processors with limited interrupt masking
support such as sh7750 and sh7780. With this patch in place we
can add logic to the intc code that merges all RTC vectors into
a single linux interrupt with proper masking/unmasking support.
Specify a single IRQ in the platform data to use this new shared
IRQ feature. Separate Periodic/Carry/Alarm IRQs are still supported.

Remove RTC register value checks from the rtc-ds1307 probe() function.
They were left over from the legacy style I2C driver, which had to defend
against finding a non-RTC chip when the driver was probed.
Also fix a minor glitch in the alarm support: DS1307 chips don't have
alarms, so name those methods after one of the chips which actually *do*
have alarms (DS1337).

rtc is clearly does not satisfy IS_ERR at the point where it is tested, so
I have changed the test to consider the just initialized rtc->rtc_dev.
The semantic match that finds the problem is as follows:
