arm64: defconfig: rebuild default configuration

Run "make defconfig; make savedefconfig" to rebuild defconfig.

This dropped the following configuration options which are nowaday's
already enabled (resp. disabled) by default:

CONFIG_MEMCG_SWAP=y
CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y
CONFIG_FSL_MC_BUS=y
CONFIG_QCOM_SCM=y
CONFIG_MFD_CROS_EC_DEV=y
CONFIG_MEDIA_CONTROLLER=y
CONFIG_VIDEO_V4L2_SUBDEV_API=y
CONFIG_DRM_DISPLAY_CONNECTOR=m
CONFIG_SND_SOC_FSL_SAI=m
CONFIG_USB_CONN_GPIO=m
CONFIG_USB_XHCI_PCI=m
CONFIG_SDM_GCC_845=y
CONFIG_SM_DISPCC_8250=y
CONFIG_SM_GCC_8150=y
CONFIG_SM_GCC_8250=y
CONFIG_COMMON_CLK_ZYNQMP=y

CONFIG_POWER_AVS was renamed to POWER_AVS_OMAP in commit bca815d6
("PM: AVS: smartreflex Move driver to soc specific drivers"). As there
are no 64-bit Arm OMAPs it getting dropped seems fair.

Note that the following user-selectable configuration options have been
preserved:

CONFIG_SECCOMP=y
CONFIG_SLIMBUS=m
CONFIG_INTERCONNECT=y
CONFIG_CONFIGFS_FS=y
