Bluetooth: Controller: nRF54Lx: Use SW_SWITCH_SINGLE_TIMER

Use SW_SWITCH_SINGLE_TIMER for nRF54Lx so that fast ramp can be used, and hence support assymmetric PHYs in ACL connections. nRF54Lx radio domain does not have second timer instance to efficiently implement software switch unless a second time is used from a different power domain needed use of PPIB for the double buffered switch timer compares.
