mlxsw: i2c: Allow flexible setting of I2C transactions size
Current implementation uses fixed size of I2C data transaction buffer.
Allow to set size of I2C transactions according to I2C physical adapter
capability. For that purpose adapter read and write size is obtained
from the I2C physical adapter and buffer size is set according to the
minimum of these two values. If adapter does not provide such info,
default buffer size is to be used.
It allows to improve performance of I2C access to silicon when long
size transactions are used.
