GTA01Bv4's shipment GSM firmware should with interrupt pull high for 
wake up CPU with factory ship image. But in GTA01Bv3 has hardware design 
error that make could make resume from wake up. If it's Bv4, should be 
ok with wake up interrupt.

Not only the interrupt, but also the UART RTS/CTS behavior during resume 
already well defined at GTA01 modem. Sean_Chiang knows more in detail.

Currently only the interrupt line is verified, resume from GTA02 suspend 
with GSM wake up looks ok on hardware design level, but resume from GSM 
others Matt need do some experiment with Allen.
