Subject: [PATCH 01/13] arm64: defconfig: Enable SPI_MT65XX

Enable support for the SPI bus on pretty much every MediaTek SoC. Only
MT7621 is handled by a separate driver, all the others use this one.

It is enabled as builtin since on some platforms like mt8195-cherry, the
ChromeOS Embedded Controller is connected through SPI and it is
responsible for the regulators powering the MMC controller used for the
SD card, and thus SPI support is essential for booting.

By enabling this on the defconfig we make it effortless to test the
relevant hardware on CI systems like KernelCI.
