soc/mediatek/mt8186: Update DRAM binary from 0.1.0 to 0.1.1
For fast-k RX flow, Vref value is read from the MRC_CACHE, but the preferred RX Vref value 0xE is set, with no re-calibration. But some DRAM vendor may use higher RX Vref value, increase the default RX Vref value (from full-k reference) to make different DRAM RX Vref compatible.
BUG=b:352632973 TEST=Check the Nanya DRAM fast-k RX Vref value is normal Logs: [3732][CH0][RK0][RX] Best Vref B0 = 22, Window Min 25 at DQ5 ... [3732][CH0][RK0][RX] Best Vref B1 = 22, Window Min 28 at DQ10 ... The "Best Vref" value is the same to full-k Vref.
