CONFIG_ARCH_TEGRA_114_SOC doesn't currently enable gpiolib, which causes
numerous build problems building a Tegra kernel with only Tegra114
enabled, and not Tegra20 or Tegra30. Enable ARCH_REQUIRE_GPIOLIB to
solve this. However, all Tegra will use gpiolib, so select this option
from ARCH_TEGRA rather than each individual ARCH_TEGRA_*_SOC, to
prevent this problem for any future chips.

This patch fixes the build error when ARCH_TEGRA_114_SOC is enabled
and ARCH_TEGRA_3x_SOC is disabled.

This provides Tegra114 with its own tegra114_init_early() instead of
making use of tegra30_init_early() so that T114 build doesn't depend
on T3x anymore.

The "powered-down" cpuidle mode of Tegra20 needs the CPU0 be the last one
core to go into this mode before other core. The coupled cpuidle framework
can help to sync the MPCore to coupled state then go into "powered-down"
idle mode together. The driver can just assume the MPCore come into
"powered-down" mode at the same time. No need to take care if the CPU_0
goes into this mode along and only can put it into safe idle mode (WFI).

The powered-down state of Tegra20 requires power gating both CPU cores.
When the secondary CPU requests to enter powered-down state, it saves
its own contexts and then enters WFI for waiting CPU0 in the same state.
When the CPU0 requests powered-down state, it attempts to put the secondary
CPU into reset to prevent it from waking up. Then power down both CPUs
together and power off the cpu rail.

Be aware of that, you may see the legacy power state "LP2" in the code
which is exactly the same meaning of "CPU power down".

The flow controller can help CPU to go into suspend mode (powered-down

The powered-down state of Tegra20 requires power gating both CPU cores.
When the secondary CPU requests to enter powered-down state, it saves
its own contexts and then enters WFI. The Tegra20 had a limition to
power down both CPU cores. The secondary CPU must waits for CPU0 in
powered-down state too. If the secondary CPU be woken up before CPU0
entering powered-down state, then it needs to restore its CPU states
and waits for next chance.

Be aware of that, you may see the legacy power state "LP2" in the code

The "powered-down" CPU idle mode of Tegra cut off the vdd_cpu rail, it
include the power of GIC. That caused the SGI (Software Generated
Interrupt) been lost. Because the SGI can't wake up the CPU that in
the "powered-down" CPU idle mode. We need to check if there is any
pending SGI when go into "powered-down" CPU idle mode. This is important
especially when applying the coupled cpuidle framework into "power-down"
cpuidle dirver. Because the coupled cpuidle framework may have the
chance that misses IPI_SINGLE_FUNC handling sometimes.

For the PPI or SPI, something like the legacy peripheral interrupt. It
still can be maintained by Tegra legacy interrupt controller. If there
is any pending PPI or SPI when CPU in "powered-down" CPU idle mode. The
CPU can be woken up immediately. So we don't need to take care the same
situation for PPI or SPI.
