board: toradex: aquila-am69: Fix 16GB dual-rank DDR configuration

The 16GB dual-rank DDR configuration uses an incorrect DDRSS_PLL_FHS_CNT
value. This makes DDR initialization hang during the DDR frequency
handshake sequence.

Update DDRSS_PLL_FHS_CNT to the correct value for the 16GB dual-rank
configuration.
