[U-Boot] [PATCH v2] tegra: override compiler flags for cmd_nvedit

Override -march setting for tegra to -march=armv4t for cmd_nvedit.c
The recent change to use -march=armv7-a for armv7 caused a regression
on tegra because tegra starts boot on a arm7tdmi processor before
transferring control to the cortex-a9. While still executing on the
arm7tdmi there is a call to getenv_ulong() that causes an illegal
instruction exception if cmd_nvedit is compiled for armv7.
