arm64: defconfig: Enable missing configs for mt8192-asurada

Enable missing configs in the arm64 defconfig to get all devices probing
on mt8192-asurada based machines.

The devices enabled are: MediaTek Bluetooth USB controller, MediaTek
PCIe Gen3 MAC controller, MT7921E wireless adapter, Elan I2C Trackpad,
MediaTek SPI NOR flash controller, Mediatek SPMI Controller, ChromeOS EC
regulators, MT6315 PMIC, MediaTek Video Codec, MT8192 sound cards,
ChromeOS EC rpmsg communication, all MT8192 clocks.

REGULATOR_CROS_EC is enabled as builtin since it powers the MMC
controller for the SD card, making it required for booting on some
setups.

The MT8192 clocks are enabled as builtin for now since their Kconfigs
are bool, and will be changed to modules after those Kconfigs are
reworked.

Restricted DMA pool support is also required to get working WiFi, but
it is enabled in a separate commit since it alters behavior of other
platforms and devices.

By enabling the support for all of this platform's devices on the
defconfig we make it effortless to test the relevant hardware both by
developers as well as CI systems like KernelCI.
