PM/Domain: fix delayed genpd poweroff

The delayed genpd poweroff incorrectly powers off
the genpd for the last active device. This happens as
there is only one pending delayed poweroff work for
device(s) and only one device (last active) is not
suspended.

To fix this, the busy check for genpd with power off
delays has been updated to consider the last active
device while delayed genpd poweroff is used.

dvfs: tegra: Selectively defer DVCO calibration

Current CL-DVFS code always defers DVCO minimum rate calibration while
DFLL is sending to PMIC voltage request matching forced voltage value.
This maybe helpful on Tegra SoC with CPU power management controller
that forces voltage underneath CL-DVFS driver on exit from the idle
state.

Not deferring calibration while this enforced voltage is applied may
result in under-estimated DVCO minimum rate, and respectively inaccurate
settings for rates at/below DVCO minimum.

However, deferring calibration may result in over-estimating of DVCO
minimum rate, that in turn may increase voltage set at low rates 1 PMIC
step above Vmin, although the rates themselves would be accurately set.

This commit added TEGRA_CL_DVFS_DEFER_FORCE_CALIBRATE flag that allows
to enable calibration deferral per-Soc, or per-platform from DT.

Set this flag for all T132 SoC platforms, where above trade-offs were
resolved in favor of deferral.

because XHCI driver keeps HSIC bus in IDLE too early before it can
properly handle HSIC CONNECT from modem. Now XHCI driver will only keep
bus in IDLE after client enables HSIC power through sysfs node, so we
boot modem early when driver is loaded.

This change also cleans some codes.

platform: tegra: add a system reboot handler

Register a new handler with the system so that it can be called before
the system restarts. The handler gets called from machine_restart()
and receives all the restart commands.

PSCI v0.2 adds its own restart handler during psci_init(). In case the
platform does not support PSCI v0.2, we use our own handler instead.

Testing - Verified that the 'reboot' command works as expected. A sample
command and output pasted below.

arm64: use common reboot infrastructure

Commit 7b6d864b48d9 (reboot: arm: change reboot_mode to use enum
reboot_mode) changed the way reboot is handled on arm, which has a
direct impact on arm64 as we share the reset driver on the VE platform.

The obvious fix is to move arm64 to use the same infrastructure.

kexec: migrate to reboot cpu

Commit 1b3a5d02ee07 ("reboot: move arch/x86 reboot= handling to generic
kernel") moved reboot= handling to generic code.  In the process it also
removed the code in native_machine_shutdown() which are moving reboot
process to reboot_cpu/cpu0.

I guess that thought must have been that all reboot paths are calling
migrate_to_reboot_cpu(), so we don't need this special handling.  But
kexec reboot path (kernel_kexec()) is not calling
migrate_to_reboot_cpu() so above change broke kexec.  Now reboot can
happen on non-boot cpu and when INIT is sent in second kerneo to bring
up BP, it brings down the machine.

So start calling migrate_to_reboot_cpu() in kexec reboot path to avoid
this problem.

kernel/reboot.c: re-enable the function of variable reboot_default

Commit 1b3a5d02ee07 ("reboot: move arch/x86 reboot= handling to generic
kernel") did some cleanup for reboot= command line, but it made the
reboot_default inoperative.

The default value of variable reboot_default should be 1, and if command
line reboot= is not set, system will use the default reboot mode.
