Simon Goldschmidt 430b42f76a arm: socfpga: remove re-added ad-hoc reset code
commit c5de2b7eae ("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,
commit c1d4b464c8 ("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: commit c1d4b464c8 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA")
