[U-Boot] [PATCH] arm: socfpga: fix 3 boards missing env var "socfpga_legacy_reset_compat"

[Simon Goldschmidt]

This fixes 3 boards that don't use CONFIG_EXTRA_ENV_SETTINGS from
socfpga_common.h. They need to enable reset manager compatibility
mode unless all peripheral drivers in Linux support reset handling.

Fixes: commit 4b2e32efa4e7 ("arm: socfpga: gen5: deassert peripheral reset by default")
