ARM: shmobile: defconfig: Refresh for v6.19-rc1

Refresh the defconfig for Renesas ARM systems:
  - Enable Renesas RZ/N1 ADC support,
  - Drop CONFIG_RPCSEC_GSS_KRB5=n (no longer auto-enabled since now
    commit 324be6d ('Revert "SUNRPC: Make RPCSEC_GSS_KRB5
    select CRYPTO instead of depending on it"')).
