Currently the LEDs are being accessed directly from within the
l1_if.c file. So the handling of rf mute and activate/deactivate both
access LED_RF_ACTIVE directly. This may lead to an inconsistent LED
status.
This patch replaces these calls to sysmobts_led_set() by an abstract
equivalent bts_update_status(), that uses a set of independant status
ids. The associated values can than be combined into a visible LED
status. Currently LED_RF_ACTIVE is on iff BTS_STATUS_RF_ACTIVE is set
and BTS_STATUS_RF_MUTE is not set.
