ESTEEM192E: adjust linker script to grown code size

Once more, some of the previous changes caused the code to grow, which
causes errors like

u-boot.lds:74 cannot move location counter backwards (from 40008384 to 40008000)

when building with some older tool chains (like ELDK 4.2).
Adjust the linker script to make fit again.
