We know how many bytes the EC should be sending us (which is also the
number of bytes transferred) and also how many bytes the EC actually
wanted to send to us. When computing the checksum and copying back
data let's make sure we take the lesser of the two of those. We'll
also complain if the EC tried to send us too many bytes. The EC
sending us too few bytes is legit for when we send the EC an invalid
command.
This is based on similar code in cros_ec_spi.

If we receive EC interrupts after the cros_ec driver has probed, but
before the cros_ec_keyb driver has probed, the cros_ec IRQ handler
will not run the cros_ec_keyb notifier and the EC will leave the IRQ
line asserted. The cros_ec IRQ handler then returns IRQ_HANDLED and
the resulting flood of interrupts causes the machine to hang.
Since the EC interrupt is currently only used for the keyboard, move
the setup and handling of the EC interrupt to the cros_ec_keyb driver.
