ramips: ER605v2 fix LED function definition

commit 665c2154ef122d10dfffeca95538ebdff82653b5
added support for ER605v2

All three LEDs where configured with LED_FUNCTION_STATUS
which worked for 23.05 and kernel 5.15.

With the upgrade to kernel 6.6 this leads to a name collision.

Therefore the USB and Power LED now use the common.h function
LED_FUNCTION_USB and LED_FUNCTION_POWER respectivly.
