spi: SPI_AXIADO should depend on ARCH_AXIADO

spi: SPI_AXIADO should depend on ARCH_AXIADO

The Axiado DB-H SPI controller is only present on Axiado AX3000 SoCs.
Hence add a dependency on ARCH_AXIADO, to prevent asking the user about
this driver when configuring a kernel without Axiado SoC Family support.
