i2c: i801: Fix resume bug
commit 66d402e2e9455cf0213c42b97f22a0493372d7cc upstream.
On suspend the original host configuration gets restored. The
resume routine has to undo this, otherwise the SMBus master
may be left in disabled state or in i2c mode.
[JD: Rebased on v5.8, moved the write into i801_setup_hstcfg.]
