MT6572不识别sim卡

【Description】
Modem boot up fail，SIM卡找不到
【Analyse】
modem没有正常工作，位于modem端的SIM卡找不到是很自然的事情。
从kernel_log.boot看到modem boot up fail log如下：

【Solution】
MT6572上modem相关的文件rename方式有变，请务必参考Pre-
Release_ReleaseNote_for_MT6572_JB3.xls的Build_Configure_Modem_MOLY页中的命
令规则给modem相关文件重命名。
例如以上log，rename为：
TG File
(MOLY project with "_TDD128HSPA")
Build_Configure_Modem_MOLY内容为：
<Add “_1_tg_n” as suffix>
catcher_fiLTEr_1_tg_n.bin
BPLGUInfoXXXXXX_1_tg_n
XXX_PCB01_XXX_1_tg_n.elf
DbgInfoXXXX_1_tg_n
modem_1_tg_n.img
(rename)
modem_1_tg_n.mak
(rename)
Build_Configure_Modem_MOLY内容为：
