The generic clocks request and preparation have been moved from
stmmac_dvr_probe()/stmmac_init_ptp() to the stmmac_probe_config_dt()
method in the framework of commit f573c0b9c4e0 ("stmmac: move stmmac_clk,
pclk, clk_ptp_ref and stmmac_rst to platform structure"). At the same time
the clocks disabling and reset assertion have been left in
stmmac_dvr_remove() instead of also being moved to the symmetric
antagonistic method - stmmac_remove_config_dt(). Due to that all the glue
drivers probe cleanup-on-failure paths don't perform the generic clocks
disable/unprepare procedure, which of course is wrong. Fix it by moving
the clocks disable/unprepare methods invocation to the
stmmac_remove_config_dt() function.
Fixes: f573c0b9c4e0 ("stmmac: move stmmac_clk, pclk, clk_ptp_ref and stmmac_rst to platform structure")
