Code updated to do case insentive comparisons for direction
& polarity, when read from Entity-manager.
Tested:
1. Verified gpiodaemon exposes all the objects as before using busctl
2. verified ipmitool chassis status still works (ascertaining the whole
flow is good)

During the object addition in Gpio daemon, InterfaceAdded signal
will be generated which contains all property values. Need to
block generating PropertiesChanged signal during this time, as
there was no property changed. Generating PropertiesChanged signal
during start-up will also confuse Buttons or any other application
which monitors this signal, hence it has to be avoided.
Tested:
1. Verified InterfacesAdded signal is properly generated during
startup
2. Verified PropertiesChanged signal is properly sent out, when
there is gpio value change.

1. Added property SampledValue, which will reflect the gpio
value status always, will be used when ignore property is true
2. Removed enabled property, as it is not used anymore
3. Fixed bug for Value property which had the inversion first
before comparison.
Tested:
1. Verified the behavior using D-Bus commands
2. Verified Power-up / Gpio Sampling / etc, along with
Buttons & set-passthrough patch.

Simplified Gpio daemon service and it's corresponding
members. Buttons must use these gpio daemon instead of
directly queriying gpio. Daemon will send out properties
changed signal, when there is change in gpio value.
Introduced Ignore property, if set true will return
cached values for the specified gpio.
Gpio daemon will query objects from entity manager and
initialize accordignly. Restarting gpio daemon, will
re-init these pins as per the entity manager.
Tested:
1. Verified the properties of Power button & Reset button
2. Performed FP buttons operation and made sure power button &
reset button properties changed signals are properly sent out
3. Testd against updated buttons code (which uses gpio daemon)
and verified basic power operations both from front panel and
from ipmitool power
4. Verified object creation, during gpio daemon restart
and also on entity-manager restart

This commit fixes the 'Value' property handling code to make it
available only on output GPIOs.

Setting of 'edge' property on an output GPIO causes this warning
in kernel:
gpio gpiochip10: (1e780000.gpio): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ
This commit make it does the 'edge' setting only on input GPIOs
to fix the issue.

Only gpio with direction set as "input" are monitored. Each gpio by
separate GpioState class. Presently only gpio "value" property is
monitored by looking into file descriptor of /sys/class/gpio/gpioXX/edge.
Planning to be changed into gpio cheracter device soon.

Service name is "xyz.openbmc_project.Gpio" with below properties:
.Direction
.Enabled
.Value
Whenever "Enabled" is set to "false" the "Value" and "Direction"
properties cannot be overridden.
