can: m_can: remove redundant check for pm_clock_support

Browse Source 
m_can_clk_start() already skip starting the clock when
clock support is disabled, remove the redundant check in
m_can_class_register().

This also solves the imbalance with m_can_clk_stop() that is called
afterward in the same function before the return.
