media: allegro: fix log2_max_poc in firmware 2019.1
The log2_max_poc field is used to set log2_max_pic_order_cnt_lsb_minus4
for the coded stream. It has an allowed range of 0 to 12.
param contains the value without the minus4, but since firmware
version 2019.1, the value has to be log2_max_pic_order_cnt_lsb - 1,
presumably to fit the maximum value of 16 into a 4 bit field.
The driver does not support firmware version 2019.1. Thus, change the
behaviour starting from firmware version 2019.2.
