There has been an update to the Bspec in which we need to set tx_misc=0x5 field for C20 TX Context programming for HDMI TMDS for Xe2_LPD and newer. That field is mapped to the bits 7:0 of SRAM_GENERIC_<A/B>_TX_CNTX_CFG_1, which in turn translates to tx[1] of our state struct. Update the algorithm to reflect this change.
