[PATCH] spi: Kconfig: spi-synquacer: Added ARM and ARM64 dependence

[Masahisa Kojima <masahisa.kojima@xxxxxxxxxx>]

kbuild test reported that Alpha and some of the architectures
are missing readsx/writesx functions.
spi-synquacer driver is only targeted for arm and arm64 platforms.
With that, added ARM and ARM64 dependence in Kconfig.
This patch also specifies the default compile type as module.

Fixes: b0823ee35cf9b ("spi: Add spi driver for Socionext SynQuacer platform")
