arch/arm/mach-axxia: Support for DDR Retention Resets

The Axxia hardware makes it possible to reset the system without
losing the contents of memory.  This commit adds the ability to
initiate a reset in such a way that memory contents are not
lost.

LSI AXM55XX: Add PMU support

This patch adds PMU support to the Axxia AXM55xx platform. Note that
on this platform, all PMU IRQ lines are OR'ed together into a single
IRQ, and therefore, this implementation uses a rotating IRQ affinity
scheme to deal with it.

arm/mach-axxia: Updated PCIe driver to set PCIe BASE_ADDR1 register

Updated PCIe driver to set PCIe BASE_ADDR1 register to 0x0 without
which PCIe inbound access wasn't working and we were seeing several
suprious PEI interrupts including BAR mismatch interrupt.

arch/powerpc: Backport of 32dda05f4ec2b854b594bd91590c46c5197d77e1

Otherwise, we get a debug traceback due to the use of
smp_processor_id() (or get_paca()) inside hard_smp_processor_id().
mpic_host_map() is just looking for a default CPU, so it doesn't matter
if we migrate after getting the CPU ID.

arm: mmu: Fix truncated 40-bit physaddr (LPAE)

Wrong type for parameter 'phys' caused adress to be truncated to 32-bits,
causing iotable_init() to produce wrong MMU mappings on LPAE system.

arm/mach-axxia: Same build for HW and simlation.

Removed the config ARCH_AXXIA_SIM, that used to identify builds for simulator.
The same build can now be run on both hardware and simulation platforms, using
different DTBs.

arch/arm/axxia: Updated Device Trees for LSI Axxia Simulation

By default, the simulator only support 4 cores; the normale device
tree, axm55xxsim.dts, now matches.  A 16 core dts is provided as well
for the more adventurous.

i2c-axxia: Support I2C_M_RECV_LEN

Add support for the I2C_M_RECV_LEN flag to enable SMBus block data transfers.

This patch also fixes an issue where the master failed to perform a proper
repeated start, but instead issued a stop followed by a start. This behaviour
confused some SMBus slave devices.

The STOP-START was caused by the use of the automatic mode of the controller.
By using manual mode the driver gets control over when a STOP condition is
signalled.
