Powering off the boot core on some Tegra platforms is not

Tegra210 and Tegra186 implement this restriction.

Tegra210: trigger CPU0 hotplug power on using FC

Hotplug poweron is not working for boot CPU as it's being
triggerred using PMC and not with Flow Controller. This is
happening because "cpu_powergate_mask" is only getting set
for non-boot CPU's as the boot CPU's first bootup follows
different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
during power on. This will ensure only first bootup on all
CPU's is using PMC and subsequent hotplug poweron will be
using Flow Controller.

Tegra210: secure PMC hardware block

This patch sets the "secure" bit to mark the PMC hardware block
as accessible only from the secure world. This setting must be
programmed during cold boot and System Resume.

The sc7entry-fw, running on the COP, needs access to the PMC block
to enter System Suspend state, so "unlock" the PMC block before
passing control to the COP.

Tegra: support for System Suspend using sc7entry-fw binary

This patch adds support to enter System Suspend on Tegra210 platforms
without the traditional BPMP firmware. The BPMP firmware will no longer
be supported on Tegra210 platforms and its functionality will be
divided across the CPU and sc7entry-fw.

The sc7entry-fw takes care of performing the hardware sequence required
to enter System Suspend (SC7 power state) from the COP. The CPU is required
to load this firmware to the internal RAM of the COP and start the sequence.
The CPU also make sure that the COP is off after cold boot and is only
powered on when we want to start the actual System Suspend sequence.

The previous bootloader loads the firmware to TZDRAM and passes its base and
size as part of the boot parameters. The EL3 layer is supposed to sanitize
the parameters before touching the firmware blob.

To assist the warmboot code with the PMIC discovery, EL3 is also supposed to
program PMC's scratch register #210, with appropriate values. Without these
settings the warmboot code wont be able to get the device out of System
Suspend.

Tegra210: support for cluster idle from the CPU

This patch adds support to enter/exit to/from cluster idle power
state on Tegra210 platforms that do not load BPMP firmware.

The CPU initates the cluster idle sequence on the last standing
CPU, by following these steps:

Entry
-----
* stop other CPUs from waking up
* program the PWM pinmux to tristate for OVR PMIC
* program the flow controller to enter CC6 state
* skip L1 $ flush during cluster power down, as L2 $ is inclusive
of L1 $ on Cortex-A57 CPUs

Exit
----
* program the PWM pinmux to un-tristate for OVR PMIC
* allow other CPUs to wake up

This patch also makes sure that cluster idle state entry is not
enabled until CL-DVFS is ready.
