phy: sparx5-serdes: remove power up of all CMUs
CMUs should not be powered up by default anymore, so remove responsible code. Signed-off-by: Daniel Machon <daniel.machon@microchip.com> Link: https://lore.kernel.org/r/20230417180335.2787494-7-daniel.machon@microchip.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
