[media] tda18271: allow restricting max out to 4 bytes
By default, tda18271 tries to optimize I2C bus by updating all registers
at the same time. Unfortunately, some devices doesn't support it.
The current logic has a problem when small_i2c is equal to 8, since there
are some transfers using 11 + 1 bytes.
Fix the problem by enforcing the max size at the right place, and allows
reducing it to max = 3 + 1.
