[PATCH] arm64: Kconfig: provide a top-level switch for Microchip platforms

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

Microchip is the only platform that doesn't have a top-level switch for
disabling all SoC families. Align it with other platforms and update the
arm64 defconfig to keep the default config the same.
