ARM: socfpga: Actually put bridges into reset on Gen5 in bridge disable
On Gen5, the 'bridge disable' command write 0x0 to brgmodrst register,
which releases all bridges from reset, instead of putting all bridges
into reset. Fix this by inverting the mask and actually putting the
bridges into reset.
