* On samsung, kernel exposes a sysfs node to disable fastcharge at
will, depending on what the user sets in battery settings UI.
* Disabling fast charge may be useful for reducing the heat produced by
the device while charging, or for extending the lifespan of the battery
* This commit introduces the fastcharge HIDL, which writes in the node
/sys/class/sec/switch/afc_disable
0 or 1 depeding on user selection.
0 means that fastcharge is enabled, while 1 means that fastcharge is
disabled

cdev_to_watch fd causes pollOnce function return immediatly.
Because thermalhal does not monitor cdev status now,
so remove cdev_to_watch fd to avoid threadLoop busy problem.
Bug: 151897840
Test: Verified thermalhal notifythrottling via emul_temp
thermalhal will not keep busy.

init_rc files require the entire interface inheritance hierarchy to
be listed, since e.g. all 1.0::IThermal functions are also implemented
by 2.0::IThermal.

enabling/disabling DT2W inside setInteractive() doesn't work correctly
on some newer samsung devices so enable/disable it only when the setting
has changed and on boot

This avoids that we enter a screen state where it doesn't react anymore
if you quickly turn off and on the screen.

Samsung enables FOD in TS driver (fod_enable) at all times except
a small number of optical FOD sensor that doesn't have BiometricFeature
.FEATURE_SUPPORT_AOD. As optical type sensor support is not implemented
currently, this HAL is only used on device that has FOD always-on.
This change follows behavior of stock firmware and without toggling of
FOD enable state FOD should be more stable.
Plus it allows setInteractive and config_powerDecoupleInteractiveModeFromDisplay
to function properly with FOD. Currently setInteractive(0) happens before
a onShowFODView (which is the current point to call fod_enable) can be
triggered by the Doze, as TS driver only handles command when it is enabled,
FOD doesn't work when there is a setInteractive(0) that disables TS.

Samsung's proximity sensor type is binary in nature.
There are only two state: FAR and NEAR.
However, Samsung uses values between min and max for
other purposes like proximity detection during Always-On
Display.
This breaks proximity detection during Doze for AOSP as
AOSP only considers the proximity sensor in FAR state
when the value equals or larger than max.
Thus, this change sets the max to 1 so any > 1 value
would be considered as FAR and the behavior of this vendor
proximity sensor type matches the behavior expected by AOSP.

We found that stock firmware calculates the fod rect
from resolution and a set of inscreen fingerprint
sensor position data at boot and then use set_fod_rect
command to tell the Kernel TSP driver.
Then the Kernel TSP driver wrote it to "sponge"
(presumably firmware of touchscreen panel).
It is not yet known what exactly was done with this
data but it is good to keep in line with stock
firmware when we can.

Enabling sensor on Press is slow and frequent on/off
switching on Press/Release leads to unexpected results.
Looking into Kernel, the purpose of FOD_ENABLE/FOD_DISABLE
commands are to save battery. (ts->lowpower_mode) It is not
meant to handle fingerprint authentication on Press/Release.
It is expected that FOD is in ENABLED state whenever the user
is EXPECTED to use fingerprint authentication soon.
Thus, this patch moved FOD_ENABLE/FOD_DISABLE from
OnPress/onRelease to onShowFODView/onHideFODView so the
fingerprint authentication can be faster and the logic makes
more sense.

Samsung uses their own com.samsung.sensor.physical_proximity
type instead of SENSOR_TYPE_PROXIMITY of Android.
This makes proximity sensor unavailable for us as we only
look for SENSOR_TYPE_PROXIMITY.
Thus, this change maps Samsung's vendor-specific proximity
sensor type to generic one.

Samsung uses a permission com.samsung.permission.SSENSOR
for Samsung-specfic sensors. Android obviously does not
have that and the default is denied when there is no
permission. As such, those sensors are inaccessible.
Thus, this change removes this permission from those sensors
so we can use them.
Android does not require special permissions for most sensors
so this change doesn't attach additional permission requirements
to those sensors.
However, note that it is possible that some sensitive sensors
introduced by Samsung in the future may use SSENSOR permission
and for privacy reasons they should be handled separately with
appropriate permission control attached.
