ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

Turned out that WFI doesn't work reliably on Tegra30 as a trigger for
the power-gating, it causes CPU hang under some circumstances like having
memory controller running of PLLP. The TRM doc states that WFI should be
used for the Big-Little "Cluster Switch", while WFE for the power-gating.
Hence let's use the WFE for CPU0 power-gating, like it is done for the
power-gating of a secondary cores. This fixes CPU hang after entering LP2
with memory running off PLLP.

It is likely that returning returned by 'devm_ioremap_resource()' is
expected here instead of something related to 'base' which should be a
valid pointer at this point.

Tegra132 and Tegra210 support the flowctrl module and so add initial
support for these devices.
Please note that Tegra186 does not support the flowctrl module, so
update the initialisation function such that we do not fall back and
attempt to map the 'hardcoded' address range for Tegra186. Furthermore
64-bit Tegra devices have always had the flowctrl node defined in their
device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra
devices.

Add a simple platform driver for the flowctrl module so that it gets
registered as a proper device.

The flowctrl driver is required for both ARM and ARM64 Tegra devices
and in order to enable support for it for ARM64, move the Tegra flowctrl
driver into drivers/soc/tegra.
By moving the flowctrl driver, tegra_flowctrl_init() is now called by
via an early initcall and to prevent this function from attempting to
mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()'
is also added.
