Modified Files:
        src/sys/dev/i2c: tcakp.c

Log Message:
- Don't use I2C_F_POLL.
- Don't access the i2c from hard interrupt context.  Instead, schedule a
  soft interrupt to do the real work.  (No need to mask the interrupt
  source, since this device has an edge-sensitive interrupt per the DT
  info; will need to be revisited if there's ever a flavor that uses a
  level-sensitive interrupt).
- Split out the i2c bus acquire / release from the register read / write
  functions, allowing us to batch several i2c transactions under a single
  acquire / release cycle.
