meta-ampere: mtmitchell: led: update led configuration

Update LED names to follow LED name convention at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/leds/leds-gpio.yaml
Also add more LED groups that applications might potential use.

Tested:
1. Check LED group in dbus to have expected groups
root@mtmitchell-dcscm:~# busctl tree xyz.openbmc_project.LED.GroupManager
`- /xyz
  `- /xyz/openbmc_project
    `- /xyz/openbmc_project/led
      `- /xyz/openbmc_project/led/groups
        |- /xyz/openbmc_project/led/groups/bmc_booted
        |- /xyz/openbmc_project/led/groups/enclosure_identify
        |- /xyz/openbmc_project/led/groups/enclosure_identify_blink
        |- /xyz/openbmc_project/led/groups/fan0_fault
        |- /xyz/openbmc_project/led/groups/fan1_fault
        |- /xyz/openbmc_project/led/groups/fan2_fault
        |- /xyz/openbmc_project/led/groups/fan3_fault
        |- /xyz/openbmc_project/led/groups/fan4_fault
        |- /xyz/openbmc_project/led/groups/fan5_fault
        |- /xyz/openbmc_project/led/groups/gpio_fault
        |- /xyz/openbmc_project/led/groups/overtemp_fault
        |- /xyz/openbmc_project/led/groups/power_on
        |- /xyz/openbmc_project/led/groups/psu_fault
        |- /xyz/openbmc_project/led/groups/ras_ue_fault
        `- /xyz/openbmc_project/led/groups/systemFault
2. Check journal log to ensure no error related to LED configuration.
