xilinx: Disable SPL_OS_BOOT for Zynq and ZynqMP

The commit 210702ae6ce8 ("spl: spi: fix falcon mode for spi boot") fixed
the logic of spl_start_uboot() where 0 means OS boot and 1 means u-boot.
Zynq/ZynqMP enable OS_BOOT by default but it was never really be used
that's why disable it to boot via U-Boot phase all the time.
