i2c: pm_smbus: Add the ability to force block transfer enable

Browse source 
The PIIX4 hardware has block transfer buffer always enabled in
the hardware, but the i801 does not.  Add a parameter to pm_smbus_init
to force on the block transfer so the PIIX4 handler can enable this
by default, as it was disabled by default before.
