If the PCF2127/2129 has lost all power and is then powered again it goes

If the PCF2127/2129 loses power it needs some initialization to work
correctly. A bootloader/firmware might do this. If not we should do this
in the driver.
Changes for v2:
- make commit log and comments more clear
- check if PORO was really disabled

The datasheet of the PCF2127 states,it is recommended to process an OTP
refresh once the power is up and the oscillator is operating stable. The
OTP refresh takes less than 100 ms to complete.

x27;ve seen on the PCF2127 and PCF2129 there is not
interrupted gernerated at the interrupt pin (INT), as long the PORO bit
is set. This behavior is not documented in the manual.

prevents the upper 16 gpios per bank to be used as wake source.
The first patch fixes the assignment for the irq_high. The second patch
adds proper return values. Which should make finding any problems in the
future much easier.

Errors from enable_irq_wake() in gpio_set_wake_irq() were silently ignored.
Thus led to the problem that gpio_set_wake_irq() always returned
successfully, even if enable_irq_wake() returned an error.
