readme: fix gpio config example

Commit eea8a4a5 renamed the group config key from `gpio_config` to
`group_gpio_config`. Reading a single GPIO pin is done within the
GPIO definition object.

When using the example, it'll result in a SIGABRT because it fallbacks
to the non-group parsing, expecting either a pin or num:

```
Start Phosphor buttons service...
terminate called after throwing an instance of 'nlohmann::json_abi_v3_11_3::detail::out_of_range'
what(): [json.exception.out_of_range.403] key 'num' not found
```

Tested: Start phosphor-buttons with the new example config does not
result in a SIGABRT.

Support multi power buttons with multi behaviors

For supporting more-than-one power buttons behaviors,
add new matches and instances by following json config.

This change is for multiple slots integrated on one chassis,
and each slot has button to control power status.

For example:
/xyz/openbmc_project/Chassis/Buttons/Power01 for button on slot1
/xyz/openbmc_project/Chassis/Buttons/Power02 for button on slot2

Moreover, support multi-level power control by json config,
chassis now can do action by corresponding pressing duration.

Tested:
Press buttons and check corresponding behaviors.

Adding num key parsing

Currently there is only support for an alphanumeric references that is
decoded into a pin number. The "num" keyword supports using the pin
number directly (integer). The JSON key field determines the parsing.

It matches the support for the "num" keyword for the gpio_defs.json
seen in skeleton/libobmc_intf. If added along with:

https://gerrit.openbmc.org/c/openbmc/skeleton/+/68883

then "num" could be used for systems that have numerically labeled GPIO
pins and have multiple GPIO banks.

Add warm-reboot option support for reset button

Pressing reset button currently issues a reboot transion. However, some
platforms might expect to have force warm reboot instead. This commit
adds new reset-button-do-warm-reboot option to configure the expected
action for reset button on those platforms.

Tested:
- By default, on release of reset button, the Host is powered cycle.
- Enable reset-button-do-warm-reboot meson option. On release of reset
button, the Host is reset while Host power does not change.

Support host selector using cpld definitions

Description:
- Support host selector using cpld definitions

Design:
- Because the current structure only supports config defined by GPIO
(Yosemite V2), but there are also have the system (Yosemite V3.5)
gets the host-selector's selection from CPLD.

- So this commit is to extend the current configuration to use CPLD
definitions. Also, support adding event io from the register file
which was exported from the CLD driver.

- For example with config json below:
{
"cpld_definitions": [
{
"name": "HOST_SELECTOR",
"i2c_address": 15,
"i2c_bus": 12,
"register_name": "uart-selection-debug-card",
"max_position": 4
}
]
}

Dependency:
- CLD driver is required (link: https://lore.kernel.org/lkml/20230117094425.19004-1-Delphine_CC_Chiu@Wiwynn.com/)

Test Case:
- When ocp debug card uart button is pressed the position property on
dbus is correct.

Add serial uart mux interface class

1. This change adds the multi-host serial uart mux interface class.

In a multi-host system when the host position is changed,
then the serial uart mux is configured to enable the
respective host's serial console which is accessed via
OCP debug card.

2. Introduced two new methods in gpio.cpp
setGpioState - set state for gpio fd based on polarity
getGpiostate - get state for gpio fd based on polarity

3. Updated the readme file about details on the new gpio
configs

design : https://github.com/openbmc/docs/blob/master/designs/multihost-phosphor-buttons.md

Testing : This change is verified in yosemiteV2 platform.

Enable group gpio configuration

This change adds support to configure single
as well as group gpio config using a single api(configGroupGpio()).
This change is introduced to support the button/input
interfaces which has multiple gpios associated with them.

As an improvement reading of gpio def json file is
done once in main function rather than reading it
everytime before creating the button interface object.
