boards/m100pfsevp: Decrease DDR lane temination values to 40 ohm and increase BCLKSCLK_OFFSET 

This fixes problems with DDR training sequence on aries m100pfs board

    - Set LIBERO_SETTING_RPC_ODT_* to 6, which matches 40 ohm. Originally it was 120 ohm (2)
    - Set BCLKSCLK_OFFSET value to 5, which matches icicle board setting
