Remove multiple write enable and disable sequences of dbi registers as Tegra194 implements writes to BAR-0 register (offset: 0x10) controlled by DBI write-lock enable bit thereby not allowing any further writes to BAR-0 register in config space to take place. Hence disabling write permission only t
