arm64: defconfig: Sync some configs with savedefconfig

Some configs can obviously be removed when sync'ing with savedefconfig, as
follows:

- config SECCOMP was changed to def_bool y in commit 282a181b1a ("
  seccomp: Move config option SECCOMP to arch/Kconfig"), so no need to
  explicitly enable in the defconfig.

- config MAILBOX is already selected by some drivers enabled in the
  defconfig, so no need to explicitly enable.

- config QRTR was enabled in the defconfig from commit 1bdf91fd2a ("
  arm64: defconfig: Enable Qualcomm QRTR"). However until many kernel
  versions later in commit 231a136fdf ("arm64: defconfig: enable ath11k
  driver"), no driver depended on config QRTR - not for building anyway.
  In commit 231a136fdf, config ATH11K_PCI was enabled and this selects
  config QRTR, so there is no need to explicitly enable in the defconfig.
