52835d59fc soc: ti: Add ti_sci_pm_domains driver
Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.

This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

e13688fe61 ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM
PCI_DOMAINS config should be selected for any SoCs
having more than a single PCIe controller. Without PCI_DOMAINS
config, only one PCIe controller gets registered.

Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since
it doesn't harm even if a platform has a single PCIe port.
Also remove PCI_DOMAINS being selected from other platform
specific configs.

c12547a00d clocksource/drivers/keystone: Add the COMPILE_TEST option
Change the Kconfig option logic to fullfil with the current approach.

A new Kconfig option is added, CONFIG_KEYSTONE_TIMER and is selected by the
platform. Then the clocksource's Kconfig is changed to make this option
selectable by the user if the COMPILE_TEST option is set. Otherwise, it is
up to the platform's Kconfig to select the timer.

13ee895547 ARM: keystone requires ARM_PATCH_PHYS_VIRT
The dynamic relocation that the keystone platform performs
only works if we can pick the phys offset at boot time. It's
possible that there is another solution for this, but this
is the easiest workaround. Kernels with ARM_PATCH_PHYS_VIRT
are not portable across platforms, and I see no reason why
anyone would run a kernel without ARM_PATCH_PHYS_VIRT on
keystone.

Select the TI EDMA to be able to enable SPI driver on Keystone
SOCs. Keystone SOCs share the EDMA IP with other TI SOCs.

Note that EDMA support hasn't been added and tested yet for
Keystone SOC data(device tree), but building it, is harmless since
driver like SPI already takes care of supporting non-dma mode
in the absence of such data.

new Keystone sub-architecture in ARM.

The TCI66xxK2H Communications Infrastructure Keystone SoCs
are member of the C66x family based on TI's new KeyStone 2
multi-core SoC Architecture designed specifically for high
performance wireless and networking infrastructure applications.
The SOCs contains many subsystems like Cortex A15 ARM CorePacs,
C66XX DSP CorePacs, MSMC memory controller, Tera Net bus,
IP Network, Navigator, Hyperlink, 1G/10G Ethernet, Radio layers
and queue based communication systems.
