[U-Boot] [PATCH] rockchip: board: puma-rk3399: define ENV_SIZE for SPI FLASH

[Klaus Goger]

be942f2e0d introduced a common CONFIG_ENV_SIZE of 32k in rockchip-common.h
On puma-rk3399 with ENV_IN_SPI active we place the environment in the
gap between SPL and the FIT image. Previously undefined it defaulted to
one sector defined with CONFIG_ENV_SECT_SIZE. With the now larger
environment a saveenv overwrites the FIT image. Therefore we now
redefine CONFIG_ENV_SIZE if build for ENV_IS_IN_SPI_FLASH.
