Revert "board: zynqmp: Fix for wrong AMS setting by ROM"

This reverts commit dfbe492edef421de09617dc26805fc428440924e.
Analog bus control register should be programmed in SPL only. This commit
3414712ba8a ("arm64: zynqmp: Writing correct value to ANALOG_BUS") is
programming the same. So revert this commit.
