commitc5de2b7eae("arm: socfpga: implement proper peripheral reset") has removed the call to 'reset_deassert_peripherals_handoff()' from socfpga gen5 SPL since the reset driver now handles resets. However, commitc1d4b464c8("ARM: socfpga: Disable bridges in SPL unless booting from FPGA") has re-added this ad-hoc reset code, so that all peripherals were now again enabled instead of letting the drivers enable them by request. While at it, remove this function for gen5 as it should not be used. Fixes: commitc1d4b464c8("ARM: socfpga: Disable bridges in SPL unless booting from FPGA") Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com>
