使用digital amp时通过mtkparser从cfg音频文件转成ini格式

针对digital amp主要利用ini里的内容。driver code会依据ini format type去 parser内容给digital amp。

下面是mtkparser的格式

[INIT_TABLE]
IniFormatType = x // MtkParser 目前固定填 0 即可
count = xx; // xx 是后面部分 index 总数
index_x = AA, BB, CC; // x: 命令 index 值，从 0 开始；AA: data length，BB: I2C address CC: data

下面是声学文件cfg的格式样本。有用的字段是去除#号，干掉第一列及第二列的剩余两列。

通过5805cfg2ini_dts.sh脚本把cfg转成ini。

须转换成功最重要的是burst_page字段及grp_size字段填对。

首先看grp_size字段。从cfg文件中捞出"00 2x"字段的数据。将"00 2x"在grp_size中标记为1，cfg中第一列递增为连续的数据，所以1后面跟连续数据长度，连续被中断再次计数，直到碰到"00 2x"为止。

再看burst_page字段，以"60 01" "02 00"开头，从cfg文件中罗列出"7f 8c" "7f aa"字段后紧跟的"00 2x"数据。罗列出来的数据在grp_size中去掉1，计算grp_size中对应被去1的"00 2x" 间的数据个数，有多少个数在bust_page中补多少"x"。

凡是burst_page中有字串的，不用在grp_size中补1，在grp_size中写字串后的length长度。如"60 01" "02 00" "00 29"在grp_size中不用补1，只填字串后的length。
