The width of the R_LENGTH field of the EV_CH_E_CNTXT_1 GSI register
is 24 bits (not 20 bits) starting with IPA v5.0. Fix this.

Fixes: 627659d542c5 ("net: ipa: add IPA v5.0 GSI register definitions")

All is well on this, but I put the wrong commit hash on the
"Fixes" tag. I'll send an update soon. The correct hash is
faf0678ec8a0.
