clk: renesas: rzg2l: Remove critical area
The spinlock in rzg2l_mod_clock_endisable() is intended to protect
RMW-accesses to the hardware register. There is no need to protect
instructions that set temporary variables which will be written
afterwards to a hardware register. With this only one write to one
clock register is executed thus locking/unlocking rmw_lock is removed.
