2eaa03b5be ARM / PXA: Use struct syscore_ops for "core" power management
Replace sysdev classes and struct sys_device objects used for "core"
power management by the PXA platform code with struct syscore_ops
objects that are simpler.

This reduces the code size and the kernel memory footprint.  It also
is necessary for removing sysdevs entirely from the kernel in the
future.

0c7fbbe1a1 ARM: pxa: fix mfpr_sync to read from valid offset
Since mfpr_mmio_base[0] is not always valid on later SoCs,
fixed mpfr_sync() to read back from valid mfp offset always.

fb60870f63 [ARM] pxa: add MFP_PULL_FLOAT
There is currently an uncovered case for MFP configuration on PXAs which
is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN
bits. This case is needed to explicitly let pins float, even if the
selected alternate function would default to a configuration with a pull
resistor enabled.
