My 520-15IKB (2017) with SYNA2B33 doesn't have working VPCCMD_W_TOUCHPAD command -
it's the touchpad program switches the touchpad instead on Windows. Considering
all IdeaPads with SYNA2B33 touchpad produced in 2017/2018, it's very likely that
none of the IdeaPads with SYNA2B33 support touchpad switching via EC. So let's
add SYNA2B33 to the touchpads not switchable via EC.
