xilinx: zynqmp: disable CONFIG_SPI_FLASH_BAR
Legacy SPI flash devices used a 24-bit (3-byte) addressing scheme,
limiting the addressable memory to 16 MB. To support larger densities
(256 Mbit and higher), extended addressing schemes, such as 32-bit
(4-byte) addressing, were introduced. If the flash density exceeds
16 MB and CONFIG_SPI_FLASH_BAR is disabled, the device will use a
4-byte addressing mode.
