i2c: i2c-core-smbus: Expose PEC calculate function for generic use

Note that for this I2C-specific change, I will need acks from the I2C
maintainers to be able to include this in my tree.

i2c: aspeed: Fix unhandled Tx done with NAK

For the aspeed changes, they don't really belong here, they belong in
the aspeed tree. I see that you need them for the device to work
correctly, though. I'll need acks from maintainers to include them.

Thanks for you information.
Will separate these i2c-aspeed's patches into other independent series in next version.

i2c: aspeed: Acknowledge Tx done w/wo ACK irq late
i2c: aspeed: Add aspeed_set_slave_busy()
ipmi: ssif_bmc: Add Aspeed SSIF BMC driver
