clk: renesas: rzg2l-cpg: Reuse code in rzg2l_cpg_reset()

[ Upstream commit 5f9e29b9 ]

Code in rzg2l_cpg_reset() is equivalent with the combined code of
rzg2l_cpg_assert() and rzg2l_cpg_deassert(). There is no need to have
different versions thus re-use rzg2l_cpg_assert() and rzg2l_cpg_deassert().
