[U-Boot] [PATCH v2 10/19] arm/km: implement weak function board_spi_clam_bus/release

[Valentin Longchamp <valentin.longchamp@keymile.com>]

They are needed on all km_arm boards where we have the environement
variables in the NOR Flash. This is #ifdefed by
CONFIG_KM_ENV_IS_IN_SPI_NOR. First boards using this feature are
the upcoming boards kmcoge5un and kmnusa.
